After golf is downloaded the courses you have played appear. Problem is some disappear how can you get them back. Only have six downloaded courses on list but the first course is now no longer there ??
Unless you own a Fenix 5X, which has mapping and all 3 regional 41,000+ courses worldwide, you will only see a handful of courses downloaded to your Connect Mobile APP and synced to your Fenix 5S or Fenix 5 series watch.
You may need to either clear your downloaded courses and sync all 6 again from your Connect Mobile APP or you can try to put just that 1 course back and it may show again with the other 5.
