Two way progress sync isn't working?

Hey, I thought sync progress on the ipad would 2 way sync with PC, so it would know if I rewinded a comic on PC and it's the latest bookmark vice versa, but it seems to force what the ipads last registered page is to the PC application all the time regardless, any way to fix that?

Thanks!

I have to check what’s the logic in the server, but it could be that only forward progress is synchronized.

You can try disabling “Update local progress on sync” setting in Import -> YACReaderLibrary.
