After the update to 0.2.1 I can't view any posts via Eternity (writing this on Raccoon, my account is on Beehaw). Tried logging out and back in, then deleting and reinstalling the app and then logging back in. Still "No posts found", I can see my subscribes communities from left sidebar but they all have no posts as well. Same thing happened for me on Voyager a few months back, haven't used that since..
The main issue seems to be the instance you're (OOP) currently on. If you do not want to migrate or want to wait to see if things will get resolved you can always browse in "anonymous" mode with a different instance than beehaw.
