Free versus paid

hi

Suppose somebody has the paid version and wants to share a pro motion file with somebody who has the free version (of the exact same version number). Can both people work on the same file this way?

There are feature limitations that the paid version user would have to respect when they touch project attributes like number of layers or layer effects etc., because they would not work in the free version:
