Me and a friend tested this (both PC based) and I started a project and shared with him.
He could open it and the midi loaded fine but the two instruments I used did not load any patches.
- Retrologue 2 opened the init patch instead of the bass I had created
- Groove Agent didn’t load any kit.
- The rendered mp3 that I had added as a track and was part of the pool did not upload to VST Transit, nor did it open for my friend.
