This appears to have fixed it. I will keep en eye on it.

For the record, if I sync via USB, and everything looks fine (all album art), THEN sync wirelessly, it will overwrite the "good" USB syncs, removing the album art from them.

I hit "Sync now" (wirelessly) from MMA version 1.3.0.0664 and MMW 4.1.14.1806. Still missing a bunch of album art that shows up fine in MMW, and shows up fine in MMA if I sync via USB instead of WiFi.

Has anything been found about this issue?

Thank you for looking into it. Just for the record, I have re-synced many, many times now, trying to figure out the issue.

Has anyone looked into this, or looked at the log I sent in...?

I am having this same album art issue. ALL of my album art syncs perfectly via USB, but some of them are missing with WiFi sync. It can't be the "multiple album arts per album" issue mentioned above, because it is an issue for albums that I only have one song from...that song has no album ...

Is anyone looking into this?

Has anyone gotten WiFi syncing to work on the "final" release of Android N? USB syncing works fine for me, but WiFi won't find any MMW server.

I continue to have this issue on Android N. USB sync works fine, WiFi sync cannot find a server.

I just submitted Log ID: KMI1UF3TKY of my results. Wireless syncing results in ALL tracks being synced (or attempted), regardless of space settings.

I am having this same issue; MediaMonkey seems to ignore any "reserve free space" settings when syncing wirelessly. Syncing via USB works correctly.
