This should be fixed in latest Beta build 1.0.7.310+ has just been posted.

If you're saving content to the external sd card, then yes. Android 4.4 restricts access to sd card content on a per application basis.

Does this mean I need to use MMW when transfering music to my phone?

Hi, it is now fixed in new beta builds of MMA and MMW. You need both. Please let us know.

Before restart: UOFLZW7271
After restart: 2EQ0JVOAKA

I suggest you send a log from About screen right after you've added the files to the Playlist as well as one after restarting MMA. You may want to add log IDs here for reference.

Android 4.4.2 and the files are on a external card. Can't delete files from the external card within MMA either.

Android 4.4? Are the files on the external card?

If i add titles to a [u]new[/u] playlist in MMA and then restart MMA the new playlist is nowhere to be found. The mp3's are still there in the folders but the new playlist is gone. This problem started a few days ago. I believe there were an update but not sure.

I use MMA version 1.0.7.0295 on a Samsung S5
