The developer of Apollo said Reddit cut them off unexpectedly but he was able to make it stop crashing by deleting his token. He can no longer access anything now but at least you can go into the app.
I was hoping he put something special in like a countdown with that last update. Or that you could still open it and see something. App is totally dead.
Update: Apparently Reddit killed all the third party apps themselves early. Probably knowing we would comment only to protest and complain.
