I hadn't any problems until recently, but now when I have a missed call phone does not show any notifications in the notification bar, but if I go to recent calls I can see it as missed. The watch rings and shows the call as missed in notifications.
When I disconnect the watch (bluetooth off), missed call notifications are back to normal in phone.
I don't have other notification problems (mail, sms, etc) when phone and watch are connected. I checked all notification settings and permissions I could imagine, in both phone and watch, and everything looks normal.
