Combining Authors and Capabilities Plugin

Hi,

I created a Role that can edit and create pages or other posttypes (but not the pages of other users, only ones where your user is added as author). So a user with that role should be able to edit any page they created.
Now I also use your Authors Plugin because I need more than 1 user with that role to work on the same pages.
But that doesn’t seem work.

If User 1 creates a page, they can edit it. User 2 with the same role cannot -> (ok)

Now an admin assigns User 2 so they can both edit that page (draft). -> ok

Now both can see the page as clickable in the overview. Only User 1 can actually edit it though. User 2 gets a white screen. (403 Rest Forbidden)

That page then gets published by an admin. Now User 1 also cannot edit the page anymore (I assume because the post_author switched to the admin)

Is there any way with Publishpress Capabilities and Authors together to allow me to have roles than can only create and edit pages where they’re assigned as authors and can’t publish them?
