Hi,
Thank you for supporting us.

Happy Monkeying!!!

I'm glad to tell that it works now!!!
After installing version .0849 I was able to do a complete initial sync which took his time (approx. 90min/17.200+ tracks) but worked flawlessly. After that I added 37 tracks to the server, synced again and after approx. 10 mins. the new tracks were added to my mobile and the DB was updated and I subsequently purchased the Pro version
Great job whoever made this happen and thanks to all of you who helped to solve it.

Is that with the latest beta (build 849) as that's available now.

Playing with it a bit more, it's working. I'm not sure which of the changes I made was the remedy. I changed the auto-conversion settings, but I also deleted all of the content within the Android "music" folder.

Ran a sync and it worked.

This just started happening to me too after a reinstall

Thanks so far. Any idea when it will be out?

This should be fixed in next beta release.

I was able to replicate it on one of my phones, tracked at http://www.ventismedia.com/mantis/view.php?id=15479

I see "Synchronization timeout" in your log. So it looks like that response from server did not arrive in a time limit. I will do more test asap.

well explained log ID is ISIA1BP6TT

Once something goes wrong, go to Menu (three dots) and About and you send a log. The LogID will show when you send one.

Thanks Lowlander for replying but I unfortunately do neither know how to produce a debug log nor how to reply with a logID

Send a debug log from MMA (from About) when you see this and reply here with a logID. It likely is a time-out problem due to the large amount of files being processed.

I have the same situation here as kmichael. The first synchronization was done via USB (about 17,000 MP3 files) and although it took some time, of course, it worked flawlessly. When trying to sync via Wifi, I get exactly the same messages as kmichael. My MMW version is 4.1.23.1881 (Gold) and MMA is 1.3.3.0842 (Standard).

Which version of MMA and MMW and assuming you're doing a wifi sync? What amount of files do you have on your device already and how large is your sync list?
