I'm not receiving notifications when portal is under attack, mentioned in comms and sometimes when it worked, it disappears quickly where it supposed to be viewable on notification tab.
Device: Realme 5

Except for iPhone models.

Are you sure, that this notification-problem is only with Ingress app?
If you block the app background activity - it fail to send you notifications
