Edit Storyline file- not original creator

Hi Claire,

Thanks for reaching out!

There isn't a way for multiple authors to work on a single Storyline 360 project file. You can however use the Shared Team Slides feature to quickly share slides and entire projects with team members, allowing them to work on the same content you are working on.

Hope this helps!
