Funny thing is that the notification bell in the navigation bar is working and opens notifications when clicked on.Only bottom bar visible is a Huawei issue. I also get it sometimes on my girlfriend's P30 Pro. This is not so much an AAWireless issue, but more a phone side issue. There's not so much we can do about that. These phones are not officially supported by Google for Android Auto Wireless, there's a reason for that. (Well at least until they maybe eventually get Android 11).
We might put a big disclaimer on the main page of Indiegogo about this, I'll talk to Emil about this.
Do you have any idea what behavior on the user/phone side exactly triggers this issue?
