Hello,
I am experiencing a strange situation with dynamics 365 model-driven apps.
I assigned the same security roles (app access and (customer service rep or salesperson)) for 12 users in my environment.
Some users can see and access the apps (Sales and Customer service) while others cannot.
I have used the App access checker. Below is a screenshot.
Roles assigned to all users:
Customer Service:
Sales
Users that have access:
Users that do not have access
Customer service Hub Roles Access:
Sales Hub Roles Access:
