Whatsapp calls and messages notification bug

[Mansoor102]

Since the time upgraded to One UI 4.0 (Android 12), I am facing issue with WhatsApp calls and messages while phone is locked. When I unlock it, all notification comes up all together. Any lead to resolving such issue?

Try uninstall and re-install whatsapp.
