We have multiple VS Enterprise subscription users using Microsoft Test Manager (MTM) within Azure DevOps without issue. A new user with Basic Access Level with a purchased Test Manager extension cannot create or edit existing test plans.
Within Organization Settings - Users the Test Manager extension is listed, but it has a warning symbol next to it. The hover text states the following:
This extension is paid for or has some assignments and is not installed on the organization. Users will not have access to give extension without installation.
What do I have to do to install it on the organization? The Test Manager extension available through Marketplace is for TFS. I assume this extension is already installed within my organization because multiple users are actively using it.
I have added and removed the Test Manager extension from the Basic user multiple times. When I remove the extension and go to add it, it tells me that I have one license available.
First, you can check whether the user's test permissions are set to Allow. e.g: the permissions in the following figure
In addition, there's a recent event that could cause this problem and we have resolved it. You can track this issue in this URL：https://status.dev.azure.com/_event/126800126 . If any progress, we will update this event log.
Hope this helps.
