iOS17 and macos sonoma, no parallel sync andymore (Garmin Connect and Garmin express) - "disconnects from account"

I habe upgraded to iOS17 and Macos sonoma. I installed the latest updates.

I got a new watch and connected it through Garmin Connect and later to Garmin Express. When then connecting it via USB to Garmin Express it says "watch is connected to another account, disconnect it from other account". Of course I only have one Garmin account and they should be connected to the same account. So I disconnected it, not knowing what Express app wanted from me because I only have one account. I needed to install various maps which is why I needed to use macos Garmin Express. So now I wanted to connect the watch to my iPhone and I can't sync anymore, Garmin Connect doesn't connect to my watch even so it is connected in the iPhone BT settings..

There seems to be a major bug either with Garmin Connect or Garmin Express. Never had that before.

Please fix this. Anyone else with this problem?

    Did you check the account Garmin Express thinks you're using? The email address (registered to below) should match what you're using on Garmin Connect app as well as Garmin Connect Web.

    Have to check this but I only have one account. I only changed email address a few months ago. Strange thing is that I got a new account here too. I never changed anything besides email once but that was a longer time ago and this problem here only is for a few weeks, maybe since updating to sonoma/iOS17.

    What I always do with new watches is set them up, updated them fully to latest version and reset them with deleting the watch from express because I have to set them up again after a reset. But still, this says connected to another account when I only have one account.
