I am sorry but I am new to Power Apps administration and I am probably making a basic error.
when I try to follow the instructions on sharing Model Driven Apps (below)
I think I create a new security setting ok, but when i come to add Security Users, the link takes me back to my Outlook 365 admin page. I created a new 'test' user there, but can't see that in the Security Users list. What am I missing?
More generally, what is the best reference for Model Driven Apps/Common Data Model Administration training?
To share model-driven apps, follow these steps.
1. Create a security role
Go to the Security Setting and create a new security role that includes all the entities used by your app. 2. Assign users to the security role
Open the Security Users page for your instance and choose the users you want to share with. 3. Add the security role to your app
From the My apps page, select the shorcut menu on your app's tile to open the Manage Roles box. Choose the security role you created in step 1. 4. Share the link to your app directly with users
