3. Everything seems OK
4. No errors reported

Same configuration, no problem. Only differences:
Uninstall -k instead of disable-usee
Samsung instead of chubot.

.. And maybe you should post in https://codeberg.org/corona-contact-tracing-germany/cwa-android/issues - its' not really a GmsCore bug.

The problem only happens on Android 8.0.0 when you don't exempt CCTG/microG from battery optimizations.
The issue is a bug in Android, #65650999.

I'll make sure we have a workaround for this in the next release.

Do you mean

pm uninstall -k com.google.android.gms
May be I do not understand correctly. (a novice here)...
If I understand correctly, the above command (-k) will not stop/remove all from running original.google.services.
