Update: This is very strange.
Without any notice TT upgraded their app to remove the user avatar from the "People" pages. Why they would do this, without coordinating with forum owners and admins, is beyond me to understand.
I guess that when TT has a bug in something and they cannot fix it, they just "remove it" without discussing it with forum admins?
Update: I worked many hours to debug this issue and then TT just deleted the feature from the app. It's a bit frustrating.. needless to say.
