Since my upgrade to marshmallow my messaging app doesn't open. I've already tried the repair using the pc software, tried safe mode, tried the clearing the messaging app storage and cache. Third party messaging apps don't work now either as the message just doesn't display after delivering. I'll get a ping that the message arrived but then I can't open the app to see it, and the third party apps open but won't show any message was even received. I'm at a loss now. Please help!
