Are you having problem with Auto-Sync syncing from device to PC or running Auto-Sync in the first place? Which version of MediaMonkey and what device are you syncing to?

its been 11 years since someone replied to this post. I have the same problem and I have upgraded to MM gold. My auto sync is still greyed out!

It seems that feature is only enabled for the "USB mass" plugin.

I would like MM to also sync "the other way round", i.e. to sync from my device to the PC.
This must be possible, but the option is greyed out in the "options for auto-sync"-tab.

Is this because I'm a free-version user?
