I experience a very weird behavior for one specific user. This person does not get the left navigation bar of a model-driven app displayed, although having exactly the same rights and being in the same security control group.
I'm not sure, if this issue is related to the fact, that this user as only one does not get the app displayed in the <company-url>.dynamics.com/apps overview (see screenshots).
I already reviewed this article (although limited to mobile and tablets, in my case this problem appears on a normal PC) without resolving the issue: https://learn.microsoft.com/en-us/troubleshoot/dynamics-365/sales/we-cannot-find-any-apps-your-role
All employees of my company have the same (basic) power apps license by default, and the app does not use premium connectors, but my suspicion still is that it's a license issue, as all other parameters are so identical.
Thanks for any hint!
