Hey Field Maps folks: I am investigating Field Maps as a candidate for geofencing on maps shared to the public. My prototype is to send a notification to the user when they are passing through one neighbourhood to another in our city. I configured the geofence with the Designer, it was super easy, this is really great. I downloaded the app on both Android and iOS. The Android experience has been seamless while the iOS experience has been rather poor.
I went to the webmap with anon Access.

I was initially asked to enable the location services

Then it asked me to access my activity.

And finally Notifications

I allowed all this and the app opened providing a notification

The issue came when I closed the app. I could no longer get notifications, and despite messing with all the settings on my iPhone that I am aware of the tool won't send me notifications. Android is a different experience entirely working every time I open and close reliably. Any reason iPhone would act this way?
Any advice is welcome.
