I am been a regular user of Zwift (PC version) since August. I never had any issue with the PC app (short of some slight display issues which appear to be well known).
I installed the brand new IOS app yesterday. My first ride was impeccable. No issues whatsoever. However, today, “all hell broke loose” during my ride from 10:15 AM to 10:40 AM EST.
I am using a iPad Air 2 with 64GB of RAM.
It started with Zwift freezing intermittently. Then, I became alone on the road. The communication with my Tacx Neo and Wahoo Tickr HR monitor kept working fine. Eventually, the screen froze for good. I then killed the app and could not open the app again (it kept crashing). I killed all the apps with the same result.
I rebooted and now it starts, pairs fine and asks me if I want to resume my previous activity. No matter what I answer, it does not respond to the feedback. My only option is the kill the app (and get to the same point again).
Correction… I just tried another time (the 10th time maybe) and I was successfully able to answer “no” and get back in the app. It is 11:07 AM in case this is server related. It now looks like it is working fine.
Internet connection is up and running with a latency to the nearest SpeedSmart (IOS Internet speed app) hub of 12 Ms, downloading at 226Mbps and uploading at 33.
