The registration flow on matrix.org was a last minute sprint to get something that works there, given we haven't finished the OIDC migration for matrix.org migration. It landed 4 days ago here: https://github.com/element-hq/element-x-android/pull/3467 and while we tried to QA it on a range of devices & OSes I'm not surprised we missed some. The good news is that it can be easily improved serverside given it's "just" a helper webapp which is doing the registration flow.
Sorry you got bitten by this. I'd be very interested if you can compare it with the flow if you specify beta.matrix.org as the homeserver.
