Dave, first, please make sure that visibility filters are not engaged; You can find them in Library, "tree dot" button in top right corner. Also if it's iTunes sync music, please make sure that all required tracks are physically available on device, not cloud items. VOX cannot play cloud items because of Apple restriction. Please share results here.
Checked filters–all seem ok. When I open Loop a few of the tracks are there, but most that I had loaded on my iPhone are still gone, even though the playlists that I had put them in are still listed. They had been on my phone for quite a while, then suddenly gone.
Actually, You should not log out from Loop at all. But once You did - yes, downloads should be done again. Otherwise it would be a mess.
That's interesting question, we thought much about what should be done with downloaded music in case of logout from Loop. Imagine if Your mail was still accessible when You logged out from Your e-mail.
Hmm. I don't understand the logic here. On iTunes when I download tracks to my phone they stay there, even if I log out of iTunes store. Why would it be different for downloading through Vox onto my iPhone? What is the point of putting music on my phone from Vox if it's going to disappear each time I log out of Loop?
I live in an area of very inconsistent cell coverage, so if I want to listen to music out of cell range I need it on my phone. I spent a lot of time sorting and organizing all that music, and it's frustrating to have to go through that again, just to have it disappear the next time!
