Old Thread Network remains in Android

Hi

I have same problem like described in other articles, that matter tries to connect over old inexistent thread network during pairing from android smartphone.

HA:
I have deleted my old Aqara thread network, deinstalled old OTBR and switched off old OTBR.

restarted HA
I then added new HA ZBT-2 OTBR and generated new Thred network.
restarted HA
added matter integration new
restarted HA
In matter integration I see new thread network under thread

I also did reset of matter/thread sensor.

Android smartphone:
deleted aqara app
Google play services for AR cache and data deleted
Google play service is not installed
App cache and data delete
newstart
When I synchronize threadaccessdata in companion app it popups that
Android preferes different data “Aqara…network” than HA.

According my understanding that is the proplem. I still do not manage to get rid of the old “Aqara…network” data that no more exists in HA.

When I try to pair my matter/thred sensors with Companion App it generates Matter data and then want to connect to sensor via old thread network. That fails logically as this does no more exist.

How can I get rid of this old thread network entry? I suppose it is somewhere cached or old factory …

Any idea?
All imputs are highly appreciated.
Thanks very much

I think for sure that it is installed, the problem might be that it has a localised name, e. g. in German it is “Google Play-Dienste”. You have to find it and delete cache and data. The internal name is “com.google.android.gms”, you can check it at the very bottom of the corresponding App Info dialog.
