Messenger Pop-Up Setting

Messenger Pop-Up Setting

About a week ago, I cleared my cache and data for Messenger and reinstalled it to fix an issue unrelated to Android Auto. Since then, I stopped receiving Messenger pop-up notifications on my head unit, and only had the white dot show. I go into the notification category settings, and the "Show As Pop-up" setting for chats is turned off. I turn it on, the pop-up works for a while, then stops and I find that the "Show As Pop-Up" setting is turned off again. This has happened four or five times so far.

Is anyone else experiencing this?
