The public documentation says that creating and running model-driven apps allows for only PowerApps Plan 2 licensed user.
But E3 licensed user can create model-driven apps but no one cannot run.
Model-driven apps created by E3 licensed users are visible to the other users who do not use Plan 2, but no one can run these apps with errors.
We are confusing about this behavior and this contains business impact for us.
Therefore, please consider to allow only Plan 2 users to create, execute, and display model-driven apps.
