Android 12.
Just upgraded to 0.10.10 and I can't seem to block communities from the infinite scroll any more.
I can tap the community avatar and block it from the community screen.
However, when I try to block from the initial post with the vertical "..." icon, I see the popup menu, but choosing to block the community does not result in the brief Toast stating the community has been blocked, ~~nor does it get added to the Block list.~~
Edit: I think it is being added to the Block list sometimes, but the Toast is definitely not popping.
Where did you downloaded 0.10.10?
I found it was available as an update in Google Play.
I installed directly from Github but its not available there. Thats so weird.
