Same happens to me specifically on climbs: if current workout section at target wattage ends during a climb, the following “free ride” section still keeps the same target wattage of the previous one. Tried disabling ERG in game, stopping and re-starting pedaling, or lowering the target bias but it still remains stuck to the previous section wattage.
All of it ends however when reaching a flat road, with the trainer eventually switching to SIM mode until next section.
Trainer: kickr core
Device with Zwift App: Dell windows 10
ANT + or BLE: BLE
ERG mode or SIM: ERG (erg would not switch off)
Trainer locked in at low wattage around 130W and it would not release or change. I tried switching erg on and off, adjusting trainer difficulty, and workout bias.

ERG
following a workout, the trainer stays in ERG mode, at the same wattage as workout cool down. Resetting zwift results in chaotic SIM experience (watts/gradient/erg fluctuating constantly)

Happening at the end of workouts where wattage is capped at last ERG target (warm down). Current workaround is to unplug trainer for 10s and plug back in.
La solución es dejar de pagar por algo que es defectuoso y los responsables de Zwift no hacen nada ni dan soluciones, llevo viendo este tema 2 años y sigue igual, la culpa es nuestra por seguir aqui pagando en vez de irnos a otro simulador.
Just for information guys I was having this issue. My set up was:
Kickr original
Windows 8.0 laptop running Zwift App
ANT+ dongle plugged into Laptop
ERG mode
AND THE PROBLEM PART - I ALSO HAD THE ZWIFT COMPANION APP open on my iPhone, using BLE. I know this has also been mentioned before on this thread and the light bulb went on as soon as I read it.
The watts were Ok at the beginning and then would get ‘stuck’ at a certain wattage and then not budge no matter whether the session increased or reduced the watts.
I tried not using the Companion App while using the ANT+ dongle. I’ve never had it happen to me since doing that. It was clearly the issue for me.
So I got a road bike and trainer and have been extremely frustrated with the workouts using ERG mode in Zwift and I’m seriously relieved, after going round and round with both Wahoo and Zwift, to hear that I’m not the only one experience this. My trainer will get stuck in the previous wattage setting and it gets worse throughout my workout. During the first 30 minutes, it will be stuck for 30 seconds to a minute. At 45 minutes to an hour into an ERG workout, it will increase to being stuck for 2 minutes to indefinite.
As an observation, it appears this issue was identified in November of 2018 and here we are 19 months later and still have paying customers seeking a solution. It doesn’t sound like the necessary resources are being put on this.

Same issue for me, Zwift is not responding to my emails or taking my issue seriously. It is demoralizing when 3/4 through 1hr+ workouts, ERG mode disables, power and cadence drops to zero and finally the trainer gets stuck on a fixed Wattage setting. Pausing the workout, adjusting the difficulty doesn’t help. I then fail to complete all the sections of the workout - I want my stars!!
I am investing my time, effort and money in this platform in return for a very negative user experience.
It is interesting that the companion app might be impacting this issue and cycling power on the trainer may help. Thanks to others on this forum for sharing your experience and suggestions, I will try them.

I had this happen for the first time this morning. Fortunately it was at the end of the workout. Watts dropped out to zero, then came back, but got stuck on my recovery wattage of 135W, and when the workout ended the watts still were stuck on 135 Closed my Zwift program and reopened it and everything went back to normal.
Running Kickr Core on a PC with Bluetooth and was running the companion app.
Update - I am very frustrated to say that this problem has reared its ugly head again. I have tried everything. The only thing I have not tried is not having my phone using Bluetooth at all while my PC uses ANT+ to connect.
I listen to music through Bluetooth earphones, playing via my phone. It is my last option but I’ll be gutted if I can’t even do that!

Hi Lucas
Yeah I did stop using ZC altogether but I still suffer with the issue. I just don’t know what it is. And thinking about it, it may well not have been ZC because that actually doesn’t use Bluetooth. It uses an internet connection.
I now have no idea what causes it. I have contacted Zwift and they just suggested not having anything that might use Bluetooth near it. In fact the list of ‘things’ that you can’t be near which might affect it sounds like you need to be in the middle of a field on your trainer (but with access to a great wi fi connection of course) to ensure it works correctly!

i had an interval workout that…wasn’t an interval workout. It was stuck at 170w, no matter what I did (other than stop pedaling). I tried + and - on the workout power, no dice. I tried totally stopping my pedaling so that ERG mode disengaged, but when I started back up, it was on 170w. I turned off ERG mode in the Android app, still stuck on 170w. I finished my workout and entered “free ride” period, still stuck on 170w.
During the workout when the new interval started, the wattage did not adjust as it should have, but was delayed for 30/40 seconds. Very frustrating because when there should have been plenty resistance there was none, and when there should have been no resistance, I had to stomp on the pedals.
Same issue as everyone, most of the time when a new interval starts there is a long delay (30-60 seconds) before the resistance adjusts. Will this issue ever be fixed? For now I am going to cancel my zwift subscription.
