Hi,
You should also go for latest MMW and MMA Beta that improves bidi sync a lot.

Did you enable the option to sync metadata back to the PC in the Device Profile (Tools > Options > Portable Device Sync)?

I am wondering why if I make an edit on my MMA (e.g. the composer, or any other field), when I sync to MMW then all the fields are overwritten with the "Old" data, that is what it was in MMW.
Is this intended (if so why?) or is it my who did not set up something (if so, where should I look to fix it?)

I have mma 1.3.1.0751 (pro licence)
MMW 4.1.18.1853 gold lifetime

i am syncing over WiFi.
