Cannot sync course with course points to GPSMAP H1

Interesting issue with Garmin Explore iOS (version 4.11) and my GPSMAP H1 (with firmware 7.07).

When I create a course in Garmin Explore app, add named course points to that course and then sync, the created course does not show up on the H1 in the Saved Data app.

If I instead try to navigate the course (by selecting the course and pressing the Navigate button with by H1 paired), a message appears that the course is synced to the device. But after a couple of seconds an error message appears in Explore that synchronization has failed.

When I create a course without named course points, the course shows up on the H1 after a sync of my library.

Anyone else seeing this as well?
