Vibrantpahadi , via OnePlus 9R Carbon Black , Sep 6, 2021 : Hey, This is some serious issue going on with OnePlus 9R. It is not displaying notification for any new message or mail I am receiving for apps like Whatsapp/Gmail etc. I can't say from how much time this issue is happening, but it happens like 3/10 times. What's this issue? I haven't changed any specific settings, it is just an unusual error which is not so frequent but occassional.
