Custom stamps are only transferred through the application settings. If you use custom stamps, and you synchronize to another device, it will copy over the custom stamp files so that the song loads properly, but it won't change the user's list of custom stamps (this is so that each user can still maintain their own list of custom stamps while synchronizing songs with other users). If you want to transfer all the custom stamps from one device to another, you have to go to Settings->Backup and Restore->Export Settings, transfer the .mcf file to the other device, and restore it under Settings->Backup and Restore->Import Settings.

The fact that the Windows version could not handle the custom stamps is concerning if this was with version 3.9.17. I may need to get a copy of the custom stamps from you (or a copy of the .mcf file). I'm using an open source library that is widely used on Windows to handle .svg files, and another open source library to use for rendering those svg files to an image (which is also widely used), so I'll be very curious to see what is failing.

Thanks,

Yes, 3.9.17. Happy to share anything in the interests of progress. Email sent.
