This happens many more times than it should.
Security is one thing but what BT's systems seem to do is ensure that no one can ever log in sometimes. Very secure and very useless.
The BT app on my android phone is set for biometric log in but I'm pretty sure that next time I try to use it I'll have to go through the whole userID typing palaver again to be told that my password is wrong and that I'll have to wait 15 minutes before I can try again. After four attempts to exit this loop I usually give up and put up with whatever BT problem I was trying to solve. If I do manage to get passed their security then it makes me set a PIN (again) after which it never uses it.
Like you, I also sometimes get told there is a problem their end and that I should try later.
For a tech company they seem very bad at coding apps to allow their customers access to their accounts. Even Microsoft don't have this problem.
