Paul_PL , via OnePlus 8T , Aug 31, 2021 : On 8T is not possible to send notifications from apps like Viber, Whatsapp, Duo ,WeChat to Samsung galaxy watch 4 released 27/8 . Is not possible to force this watch to vibrate or do signal when notifications arrived on phone 8T. On model 7T all works fine no problems. So what is wrong with 8T???
