Google maps. Near a coastline to a river
Thank you for the update. I would be happy to continue assistance. We have been researching instances of this happening and it appears to be isolated to situations where the creation of the course or editing the course takes longer than about two minutes. It also appears to be more prevalent for users in Europe. We have several research cases open regarding this issue and if you reply with your Garmin Connect username and email address I would be happy to create a new case for this. As a work around, if you create or edit a course within that two minute window, it should work fine.
We apologize for any inconvenience this may be causing in the meantime. Please let us know if we can be of further assistance.
