Connection Error when loading watchface settings via connect IQ Mobile (android)

Since today I experience issues in my Android Mobile Connect IQ.

When go to -->My Device --> watch faces --> watchface. I see 2 options, settings and delete.

When click settings the errormessage is connection error: Problem at loading of settings for this device. Try again.

Multiple retries with no success.

When connect device with USB to Windows 11 PC via Garmin express it works as normal. watchface settings can be adjusted.

Descent MK2i is properly paired with phone via bluetooth and wifi. Tried removing wifi settins and paired BT again with no success.

Even re-installed the Connect IQ app.

The problem remains persistant

Any idea's how to solve?
