Hi!
Before opening a bug report, this seemed to be a better option.
Anyway, my instance (currently on version BE: 0.19.5) hid some communities so naturally they won't be seen even on searches unless one purposefully subscribed to them. While I'm fine with this decision, there is a problem here with my case:
I can subscribe to these communities as well as post to them. However, I cannot see my own posts to these communities when I visit my profile. If I visit my profile from another instance (that didn't hid these communities), I can see my posts like this. But not from my instance.
An admin suggested that this may be a bug. What do you think about this?
