Cards disappear from Garmin Pay on the watch

Today I tried to pay via my watch and there were no cards in Garmin Pay.

This has happened already a few months ago. Since then I re-added 4 cards and even used some of them, but today the wallet was again empty. I don't remember when I upgraded to 20.31, but I guess that it was after I last used Garmin Pay, and probably the upgrade itself removed the cards? Is that normal?

Depending on where I look in Garmin Connect app I still can see the 4 cards:

More - Garmin Pay - 4 cards

Devices - fr966 - Garmin Pay - empty

Unfortunately I am not able to add my card that is already in the Garmin Pay to the watch - something that also happened last time the cards disappeared...
