Instinct 2x, left hand: Garmin pay password each time

I use Garmin Pay on my Instinct 2x without problems.

But, since I switched from right to left hand, I get asked for the password each time, even immediately after I entered it. It seemed to work on the right arm and only requires the password after I took off the watch. I switched the watch-hand in the settings.

I tried:

  • re-adding the cards into garmin pay
  • reset the password
  • to tighten the strap

Nothing helped.

Any other ideas?
