Since you're on Android 9 (and without installing Lineage/etc, there's nothing further official for that phone), ADB is the only thing that might work. I'll also note (and this is a pain and not sustainable for casual detection) that since that device CAN do "split screen" you can work aro...

The fix is in the beta channel now - it takes a few days for us to get enough feedback to start "promoting" a release into public distribution (this is a great example of a problem that never manifested in the beta channel; probably no-one with an Android 7 device is in the beta group/test...

found it - isolated to android 7/7.1, and old library got bumped and broke things on our oldest devices supported. Fix forthcoming shortly.

as an aside (not a direct response):
registering multiple accounts is never the answer. it looks like abuse to our automation.
