Whatsapp notifications
Starting a week ago, my wife says that she started to not receive whatapp notifications unless whatsapp IS open. Indeed, when I try to send her a message, my device show only "one tick" and as soon as Whatsapp is open, 2-ticks appear. Locking back her iphone immediately and sending another message goes correctly and notification appears. A minute later, while iphone is still locked, the same happens - message is one-tick, no notification.
Device is XR (and a couple of months ago, after dropping the phone, FaceID stopped working, but otherwise alll is functioning ok). iOS 15.4.1, whatsapp latest version. There is enough storage space on the phone, Whatsapp backup is around 1,9GB (so, ok). I've tried resetting network settings, no luck. The same happens over wifi and over cellular.
Anyone some ideas? Thanks
