Hey there,
I've recently been having a few issues syncing playlists from MC25 to an SD card on an S7 phone.
If I start from scratch (no music on SD card) it usually works ok, although sometimes it gets to 98% and then just sits there; if I unplug the USB then the tracks are all on the SD Card but some of the playlists are empty when selected. If it does go to 100%, when I then sync again later it doesn't recognise many of the tracks are already on the SD card and tries to sync them again. It seems that the phone is somehow altering the track's info so MC doesn't see they are already on there.
Also, when I plug my phone in it often doesn't recognize it, well it shows the phone and SD card in 'Devices' but it stays stuck on on 'working' and doesn't load the SD Card/Phone's contents until I go to unplug my phone, when everything suddenly shows for a second but of course I've just disconnected the phone so it then disappears.
I should note that the playlists go into a folder on the phone and the tracks go onto the SD Card, if that makes any difference.
Thanks for any help with this
