Notifications not coming through.

I've done a search but suspect this is a Android 13 issue. Samsung Galaxy S22 Ultra. Latest firmware and software. 

Had been noticing that after about 12 hours no notifications come through to my Fenix 7x solar. Now I can't get any notifications at all. I've tried force stopping garmin connect and restarting it. I've tried rebooting the fenix.

The weird thing is if I click my device (a watch in a circle with the green dot) I get the running man forever, even though it's showing as connected, but my live heart rate is showing in the app and is correct.

Suggestions please? I'll reboot the phone and report back but I don't want to have to do that every day without fail... Notifications were the main reason for buying the watch as I'm getting song requests on it! 

UPDATE, rebooting the phone brought the notifications back, but likely only for 6 or 12 hours or so. Watch is definitely connected when the notifications fail to appear but garmin connect can only see certain things like heart rate. I just tried clicking the device settings like before and now I get device settings fine. So device settings and notifications fail after x hours require a phone reboot to fix it? 

Thanks
