Did you tap/click the pencil icon to edit?
Those fields are still showing up for me on my Android phone:
Thanks Daren for your reply. Hmm, I see, I was looking at my âZwift Profileâ at Zwift-dot-com, but then, I notice youâre looking at a âPublic Profile.â I search Zwift HELP some more and did (1) turn on Zwift on desktop with Windows 10 (2) eventually tap on MENU when on the screen where one can actually do a ride (3) tap on the pencil in the box that Daren shows, so I can Edit. Now Iâm at a screen where I can change my max heart rate so the charts and reports all make more sense. It was set to zero, so max was set at 199 !!! According to Zwift, I was somehow doing everything in the 1st zone - almost impossible! This is the location for manually setting FTP, too. Iâd just done FTP tests so thatâs about right, maybe a bit low, but Iâm recovering from illness. BTW, once I updated this screen for Bicycling, the new heart rate and FTP show on the screen in the same location for Running. It is headed "Public Profile"and looks like the one that Daren shows. Looks like in Zwift one gets the same max heart rate and FTP for both running and bicycling though they are different sports and, at least, FTP may be different in reality.
Holy Thread revival
Reading back on this thread, itâd be a major plus if zwift would allow custom hr zones.
I often ride blocks of z2 hr, and while I know the ride will show ok in my training peaks data zwift usually shows it as a z3 into z4 ride and strava shows it as a 2/3
Having different data across platforms gets my ocd going 
Anyone else see the value of custom HR zones?

Yes. Iâve always missed that. Not that I would bother to use it much myself, but it always struck me as odd and a bit limited or lazy that this feature was never added. Itâs sort of standard with other apps. There should be a default setting (the one we have today) but it should also be possible to adjust it.
And I am amazed now, going back in the thread, how the OP could get the response he got from others participating in the thread. Dismissals like âZwift doesnât use HR zones, it uses power zones (and thatâs much better)â. They really didnât get it. Sure, power is a very nice measure we are lucky to get relatively easily compared to e.g. runners, but it doesnât change the fact that HR is absolute key to performance and (perceived) effort.
Caveat: Adjustable HR zones could be used to cover up cheating in races though. Under the assumption that a random race participant has roughly average HR zones (which may not always be true), then time distribution between the HR zones during a race (the post-race HR histograms) tells you everything about who is cruising in a lower category and who is going flat out really fighting at the upper end of a cat. But the problem here isnât really the freedom to adjust HR zones but rather the current categorization system, which needs to change, and Zwift has promised to do so.
So, in brief, I agree fully with you. It should be on their TODO list.

I am new to the community, but a very clear youtube video is available for the answer of this question

Hello, I would like to add my maximum heart rate in Zwift but canât find the right place in the app on my Mac or in the Companion Dashboard. 1. Where exactly can I find it?
2. I also have Wahoo Element, so perhaps Zwift can get the information there?
3. Where is the cadence in rpm mentioned during the ride? Iâm sure my cadence is connected (as is mentioned on the ome screen) but contrary to my heart rate I donât see it during the rides.
Thanks for your help.
Maybe for cycling but not for Ironman training. From my experience, normally age group placing one or two in 70.3 or 140.6 Ironmans. If you are doing double interval days and your runs are scheduled first, it will definitely impede your power output in the later session. Not watching your heart rate is a ticket to overtraining. Moreover, absent lactic acid testing, you are more likely to train beyond your target LT 1 or LT 2 ranges wearing on your nervous system and causing burn out. So, if youâre typical week is biking 200-300 miles, running 40-60 miles with the equivalent of 5/6 speed/threshold sessions, not counting fours hours in the pool - watching heart rate is not antiquated because it is solid metric for fatigue.

It is very refreshing that Tadej PogaÄar finds power meters âunreliableâ and âcould only use HRâ but uses power to supplement the HR numbers. Check out the YouTube short at shorts/gkMMLljI2MQ All that BS about drift is not as significant as people claim.
He wouldnât happen to be using Shimano cranks for power by any chanceâŚ?
UAE are using Shimano Dura-Ace, so itâs certainly possible. Donât know if theyâre using a built-in Shimano crank power meter.
