No notifications for messenger apps anymore?


Hello everyone,

I have an iphone XR, my son has a Samsung. we both have (older) visible plans.

Since several days (or weeks), I don't get notified in messenger apps like FB-messenger or Whatsapp, Slack, etc when a new message comes in. Also no notification when messenger-calls are coming in.

I checked all settings: 1) I haven't changed/touched them since years, 2) they are all ok, checked several times, 3) updated my iphone to iOs 16 to no avail, restart didn't help either.

When I open a messenger app, I see the messages, but again: no notification, no red balloon, etc.

My son has this problem only with the google messenger app.

As my son and I have issues: could this be a visible-problem?
