I'm using Garmin Express on a Windows 10 PC with iTunes and a Fenix 6x Sapphire. I'm using the iTunes option in Garmin Express. I have no issues with Garmin Express reading my iTunes library and I've been using music and podcast playlists for about 6 months. DRM is not an issue. All of a sudden, for specific songs & playlists, Garmin Express is not creating the playlist in full on the watch itself. I thought it might be the playlist size so I found 3 missing songs and a good one from a large playlist and created a smaller test. I sent this small playlist of 4 songs to my watch from GE. GE indicates all 5 files transferred and expanding the watch playlist in GE shows all 4 songs. All green, working just fine. However, the watch itself only shows one song in the playlist from the Music menu. If I open the M3U file on the watch from Windows Explorer, it only shows one song as expected. Why the inconsistency between GE and the watch? Furthermore, if I select all 3 album folders from Windows Explorer, then right-click, then select Create Playlist, all 4 songs are embedded in a new M3U playlist and that playlist shows up on my watch just fine. Something is obviously barfing on the write of the M3U file to the watch but I don't know what it is. Anybody had that issue? I guess my next step is to try to edit the original M3U file by copying in the contents of the Windows created one...
