Hello,
I have User A that has the security role "Field Service - Administrator".
User B has "Field Service - Ressource".
When connected to the mobile app with User A, i am able to see all the custom entities and it's forms and views.
If i connect to the mobile app with User B, i don't get any error, but i am not able to see any of the custom entites. If i check within the CRM with user B, i am able to see all the custom entities.
As you can see below, "Check" entity is one of the custom entities.
