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.
I fixed it by going into my account, hitting edit, and clicking the save button. I think there’s a bug with the expiring session not being handled. And clicking save seems to log you back in.
That fix doesn’t seem to stick. You start seeing errors again after an hour or so.
