As the title suggests. I was having multiple issues with posts, upvotes, downvotes and comments not saving.
Deleting the app and reinstalling has refreshed the whole thing and it now works better than ever.
Posting here in case anyone else had similar issues.
What the app does is not keep you logged in. You’d have to go to settings and save your username and password to be able to do anything.
Good to know, thanks!
