The support for this is utterly woeful to the point I'm starting to think it's deliberate to stop people using it.
Anyway, I managed to get mine working without them. On the mobile app I was getting the suspended message. So I restarted it and selected login/register. Instead of putting my credentials in I selected register (as if I was setting up a new account). It then gives you another screen with a login option in (I think) the top right corner. If you click that you go to a different login screen which allows you to select the "remember me" option as you login. That screen let me in. As soon as I was in I set up face id and it's worked ever since.
(Sorry if the description wasn't great but doing it from memory)
