I got a new iPhone yesterday and booked 5 separate 2-4 leg trips today trips today. I received quite a series of notifications for every C+ upgrade from the app. It was kind of annoying. Delta isn't even showing in in the list of apps under settings and I can't figure out how to shut it off, but I definitely don't want to shut off Delta alerts anyway, just these stupid upgrade notifications. Anyone know? Is there a thread I missed?
