ive found a solution for the new message glitch: when you get a new message try clicking on top of the phone where the time is, that should open the message, it only works when you get a new message notification though. other than that, you can't see any old messages besides those of Abby, Liz, and Linda sadly...
hope this helped!
Edit: I've only tried this on phone, I don't know if it works on pc!
