Dynamic brushes not exporting/importing correctly

Hello,

I’ve created several dynamic brushes and have exported them for other people to use. However, when they import the brushes, they only import with the first drawing and not the entire dynamic brush. But if I export the brushes, delete them from a new Harmony file, and import them again on my own machine (the one I used to make the brushes), they import just fine. I couldn’t find any special way to export/import dynamic brushes; am I missing something?

I’m working in Harmony 15 on a Mac.

Thanks!
