Fenix 5x Steps recorded on the watch 2 days ago but not appearing in the connect app

My steps from the day before yesterday are not syncing to the connect app. Steps before that and for yesterday and today are sync'ed to the app.

Have tried to restart all devices, reinstall connect app. logged out of garmin acounts etc. 

Nothing changes - steps for that 1 day is only showing on the watch and not in the connect app.

Please come with a solution as I have about 80 days above my 10.000 day step goal and do not want to start over again
