Their email verification system doesn't work on Android and gets you in an infinite loop where you get a verification email with the link, you click the link, it fails to pass some piece of context to the Android app (I think) and it wants you to get a verification email again.
No error messages the whole time. The system just doesn't work.
It's almost as if somebody threw the error messages into chatgpt and said "make these errors stop" and pasted code that ignores the error messages into their codebase.
