We represent an umbrella organization with several sub-organizations and a team of testers/developers. To ensure that GIS projects remain interchangeable without compatibility issues, it is important that all users work on the same ArcGIS Pro version.
Currently, each user can update his ArcGIS Pro individually with the push of a button. To prevent compatibility issues for their users, organizational administrators should have the option to both turn off the update notification for individual users, roles or groups (as described here) and additionally disable the "download now" button under "software update" in the "About" section of the "project menu" in ArcGIS Pro.
This would work well together with this idea.
