Sleep trueup cannot sync/update on fenix 6 pro

Hi,

Currently i have fenix 6 pro with firmware version : 19.20 and Garmin Express version 7.9.1.0.

I got notification 1 update available : sleepup pop up when i am connecting the Fenix 6 pro to Garmin express.

But it always failed to updated when i hit the install button. First i got notification that the app is not compatible with the watch then i tried to do some steps which were suggested on the forum.

I already deleted all fit file in the garmin sync folder on the laptop but it's not solved the issue.

I also install latest update Garmin Express but i still failed to update sleepup   with different notification, now it is said that there was error syncing with Garmin connect.

Is there anybody know this issue and how to solve it?

Thank you
