Sorry for posting this in the S9 forum but i couldn't find a S8 section. I had a S6 for many years but suddenly it stopped notifications when Whatsapp calls and even at times messages would come in. It was only when i would wake the phone from the screen going to sleep that the notifications would come through all of a sudden.
I upgraded to an S8 a few weeks back and it's been going well but now I am suddenly experiencing the same issue with this also after a few weeks of no problems. Messages seem fine but calls are not coming through at times.
Can anyone help me as this is really frustrating. I *think* it only happens over wifi.
