GMS' behavior is to show a notification, re-prompting the user to enter their password. I intended for this functionality to be added when I wrote this code:

…but then I didn't get around to implementing it. What is needed in that place is some kind of UI flow that first tells users to reauthenticate using a notification (in the background case) or directly open that page (in the foreground case). Also the background / foreground decision might still be optimized, as so far I only was able to test it for the enterprise account cryptauth flow, which won't occur for all different types of call.

I just had this with Maps, was very confusing because I thought it was due to the latest signature checking changes, but it wasn't (my phone is Jan 2025 L4M build), but actually it was just because I updated my Google password. Maybe this could be a pinned topic?

I think I was seeing a similar issue - though in my case, it wasn't just Google Maps, but the whole OS somehow became unstable: #2405
