**Additional information:**

I've had to reset my Thread / OpenThread Border Router recently and since then I can't get it to work on the Android app. I had to resort to an iPad I hadn't synced Thread before, to be able to re-pair the devices.

It seems the credentials are cached on the Android app somehow and I can't update it no matter what I try. I've done everything from clearing up cache for the HA companion app, to the Google Play Services, I've tried to force credentials resync (which is what is in the logs, but it seems it's syncing the old one: `ha-thread-cb0f` instead of the new one `ha-thread-9267`
