Edge SYNC Server Connection auth error after relogon

Dear community,

we are using RDS with Edge an a policy to force the user to login to edge with their M365-Account.

The User-Profile is saved on a shared drive and users are working with roaming profiles.

If the user logs in to edge, the sync works. After logoff and re login, the sync is disabled with the status :

In the GPO i also force the sync to be enabled and activated each "element?"

my guess is that Edge might store authentication data in the Local AppData, which gets removed upon logoff, causing sync failure upon re-login. Deleting the profile and re-logging into Edge likely regenerates this data, reestablishing a trusted authentication and "resolving" the sync issue. - just my guess.

Somebody ever faced such issue and have a fix for me ?
