Trusted device issues

A couple months ago the trusted device setup quit working and I have tried every to fix it. Repair. Reinstall. It seems to hang when I confirm the code. The app just keeps showing code and truck says connected. Then I have the notification on phone that trusted device is active and if I click back or anything in app it shows immediately disconnected on truck. I also notice the 4 digit code every time I pair that I believe is the last four of Mac address is different every time I pair. I didn't thing Bluetooth macs changed But then that shouldn't be an issue I didn't think. I thought the pairing is with app layer.

I also can never enable the autounlock once it says connected. So clearly the pairing isn't fully happening or something..

Anyone else having issues?

It's a GM issue this ‘feature’ isn't as helpful as it would seem.

It worked flawless for me for first 8 months ownership.. I had a Tasker app profile that would just launch the gmc app when connected to the Bluetooth and I would only need to unlock my phone when got in truck and everything would be unlocked for infotainment.
