This has been going on for about a week, maybe more.
I browse Active threads, post on a couple, then tap Threads I'm On. After quite a wait I get told I need to log in to access this. Obviously I have already posted a couple of times so this is confusing.
So I go to log in. My email and password are somehow already entered. Just to be safe I re-enter the password and tap Login.
'Login successful'! Yay.
Actually 'rats', because when I try to go to Threads I'm On I get the same message about needing to log in.
