[de.hochbahn.hvvswitch] says "Update Google Play services; hvv switch won't run unless you update Google Play services."

Affected app
Name: hvv switch - Mobility Hamburg
Package id: de.hochbahn.hvvswitch

Describe the bug
Starting the hvv switch app latest release from Mar 8, 2023 displays a notification

Update Google Play services
hvv switch won't run unless you update Google Play services.

The app runs though, but forcing a map to open doesn't work.

To Reproduce
Steps to reproduce the behavior:

1. Install https://play.google.com/store/apps/details?id=de.hochbahn.hvvswitch
2. Start it.
3. Mentioned notification is displayed.

Additionally:

4. Disable Location in Settings.
5. Swipe up twice to "Choose your vehicle" => displays "Your location cannot be determined precisely enough." (which was also in earlier releases, but ok).
6. Tap "Open map" => map does not open. (which was possible in earlier releases that did not display the notification).

If Location is enabled, choosing a vehicle from the then displayed map is possible.

Expected behavior
No notification, opening map works.

System

Custom ROM: LineageOS for microG 17.1

Additional context
Add any other context about the problem here.

Start by reproducing the notification and failed map opening with hvv switch on Android 10, LineageOS for microG 17.1, and microG Core 0.2.27.223616. Compare behavior with an earlier release where the map opened, then trace the relevant Google Play services compatibility and map-related entry points. Done means the notification no longer appears and opening the map works with Location disabled.
