I created a custom post "accommodation".
I used also Access to create a custom role "property manager"
I've many users with "property manager" role.
I need to set for eachone an accommodation.
I'm trying to set the user "property manager" as autohr of custom post type accommodation, but I don't see the users in the option list. I see only Administrator role users and not "property manager" users.
I set for "property manager" role all capabilities available but nothing change.
Not sure why your role wasn't working as intended.
However it should be working now. What I did was to create a new Property Manager role and set it to copy the permissions from the Author wordpress role.
