For the past two weeks the screen rotation lock no longer works while the Zwift app is up.
Device is a Samsung Note 10+ running Android V11 Last system update 1 Feb. '21
Zwift V.1.0.63186
Noticed the same yesterday. I use the Android app on my phone, and I made a DIY solution to use my Garmin Out-front mount, which is set up pretty level horizontally. The picture kept turning upside down, although I turned the automatic screen rotation off. It was really annoying.
I have the same issue. Zwift is running on my Android phone mounted to the handlebar. I use a freeroller for training and the screen rotates continously due to the movement. System level auto-rotation is turned off, but Zwift app rotates the screen anyways. It is very sensitive and rotates rapidly. I consider it is a bug.
I don’t think this has ever worked - it has always forced landscape but flips to whichever way the screen is facing.
have you tried using a screen rotation app? I have used this one before:
not for zwift but i use it to flip my screen upside down when using the companion app so that the charging cable comes out of the phone and away from the bike

I just tested two free apps for this from the play store. Neither of them stopped the screen from rotating.
Di you test the obe I linked? That one definitely works
You have to enable some permissions and enable screen rotation but then it’s fibe
Yes, that was the first one I tried. I even restarted my phone and confirmed that the app was enabled and running.
It just couldn’t prevent the screen from flipping.
Sorry I thought this was about the companion app (didn’t reread the years old thread!)
For Rotation Control, you have to have the app running, but then you have to pick the rotation you want from the pull-down menu. I use that for the Comp App too, although never with the main Zwift app. But you do need to choose your rotation, not just start the app.
Thanks, I just tested it using a landscape orientation. It does seem a bit less sensitive, but I could still get it to rotate when I flip the phone over.
Maybe that’s normal.
The app should have settings to force certain orientations. For example, an icon for a landscape screen, and then an icon for a landscape screen with an R in it. That should force landscape and upsidedown.
If you try that, and also disable the normal screen rotation on your phone…?
Yes, I did see those icons. I tested them, both with and without the R. All apps except the zwift game itself are truly locked. It’s only the zwift game that can still flip when the phone is reoriented.
Well that’s irritating. Can you turn off rotation in your regular phone settings? If you do that, does it kill the Rotation Control app? Or could that work?
Incredibly, the phone control is so sensative that even vibration can get the game twirling around 
The app it really a improvement. I will post again after my next running/riding test.
