App and cloud not working

Both app and cloud will not work, I have tried to do the new one sign in thing.
But all I get is a message saying I have a token missing and it will not let me sign in.
I have tried deleting the app and reinstalling it.
I’ve deleted the installer app and reinstalled it.
I’ve cleared data from app, Ive tried everything and nothing at all is working.
Asked in Facebook group and no one’s got a clue how to sort it.
Anyone know how or what this missing token is ?
