I'm trying to get an update finished today for Android and Windows. We can see if the update addresses the problems you are encountering. I'm not seeing any issues on my Windows devices with adding files or saving changes. If you want to share a library backup file with me that demonstrates the issue (or export a song as a .msf), I'm happy to test that to see if it seems to work for me.

Thanks,
Mike

I just emailed you some files and a longer description of the error
