A couple (?) of days ago join suddenly stopped syncing messages. I can't say I've done anything that should warrant this. I can send a note from my phone to my computer, I also get notifications on new messages - I just don't get the messages in join. Also, if I click "reply directly" (or whatever it's called), I'm just sent to the (non existant) list of messages. I've also tried opening https://joinjoaomgcd.appspot.com/, but I'm getting a brief popup before getting a message about not being authenticated. Please see the attached files.
