SkyView map 2024.30 synchronization ERROR

Hi, Fenix ​​​​7 SS,

the watch offers me a map update - SkyView 2024.30. I synchronized via Garmin Express - the update is complete and at the end the message "everything is up to date".

The map manager in the watch says: Update to 2024.30 is possible. When I started the update directly on the watch, it ends at 95 percent with an error: synchronization was not successful.

Restarted the watch and connected to the charger - the map update to 2024.30 on the watch is running, but ends with the same error ... Then I connect the watch to Garmin Express - synchronization takes place - result: everything is up to date.

Any ideas?
