CJ,I looked and don't see "Notification" anywhere in the iPhone app.
I have an I5s, with iOs 12.4.7 that is the latest and 3.10.5
I do have a tech ticket for this and to lower battery frequency to 61 Hz.
Do you have a Tesla vehicle? Some folks who do have a car are getting notifications about grid outages.
Just to be clear, my understanding is that to get notification of grid outage, there are two settings required. One is in the Tesla App: on the main screen in the upper left corner is a small gear icon which takes you the in-app settings menu where mine lacks the Notification item but has icons for Inbox, Loot Box and Video Guides and Sign Out. The other required setting is in the iPhone's own Settings App, Notifications item and the Tesla icon takes you to "Allow Notifications" and other details about what sort of notification to use.
