Description of problem, include YAML if issue is related to notifications:
When creating a new home-assistant Thread network in Home Assistant (e.g. via "Reset border router" feature in the Home Assistant Thread integration configuration page) updating the Thread credentials seems not to work.

To reproduce:

1. "Clear all data" of "Google Play services" method to make sure to start from a clear slate
2. Have a home-assistant network as preferred set in Core (say home-assistant network 1)
3. Select "Sync Thread credentials" -> "✅ Added network from Home Assistant to this device"
4. Select "Sync Thread credentials" -> "✅ Home Assistant and this device use the same network" 👍
5. Create a home-assistant Thread network e.g. by using "Reset border router"
6. Select "Make preferred network" to mark this new home-assistant network as preferred
7. Select "Sync Thread credentials" -> "✅ Updated network from Home Assistant to this device"
8. Select "Sync Thread credentials" -> "✅ Updated network from Home Assistant to this device"

Up to 7 everything is as expected. However, when trying to commission a device after step 7, it won't work because the credentials didn't really got updated. Step 8 also proves that. It seems the app is not able to update the dataset.

The current work around is to delete all Thread credentials on the device. The Thread credentials are stored as part of the Google Play services. They ca be removed using the "Clear all data" button in the Google Play service storage menu.

⚠️ Deleting Google Play services data does reset some other device settings, namely the Google Wallet cards. ⚠️

Resetting the border router in Home Assistant will result in a different border agent ID, which is what the app uses/needs to keep track of border routers, so step 7 will result in a delete + add new credential. The "deleted 1 datasets" part of the log statement is incorrect; this number is simply all datasets managed by the app so even updating an existing one will show deleted 1 updated 1 (to be fixed).

Potential library bug: https://issuetracker.google.com/issues/286158210

The example app also doesn't do anything for clearing the credential which is surprising: https://github.com/google-home/sample-apps-for-matter-android/blob/244ccdd78b7e869fe5260adbe0d051e8c9b5ee29/3p-ecosystem/src/main/java/com/google/homesampleapp/screens/thread/ThreadViewModel.kt#L133-L135

I have not yet tried to replicate this because of a Nest Hub on my network which I need to reset + keep offline while doing this to prevent it from becoming the preferred credential. Maybe/hopefully logcat on device will provide a hint what is happening inside GPS, even if it is redacted.
