since ios 15 update - apps like WhatsApp or Messenger have stopped receiving messages when the app is not open
Since my phone has updated to iOS 15, it has stopped receiving messages on apps like WhatsApp, Messenger or Instagram. Initially I thought this was a notification issue, but it seems that the apps are thinking that I’m not connected to the internet until I go and manually open the app - at which point it will update and show me any messages I have received since last time I opened it. I don’t seem to receive notifications at all. I have already checked and all apps are up to date.
