Adobe Update window repeatedly opening for users in RDS

Hi,
We are running a Remote Desktop Farm on Server 2022.
Adobe Acrobat Reader is installed & updates are set to install automatically.

As far as I can tell all servers are already running the latest version of Adobe Reader which is 26.001.21529. Yet users are being continually prompted with a pop-up window similar to the attached image.
If I log into the same server with my admin account and open Adobe to check for updates. It reports that the software is up to date.

Any ideas why this is occurring and how can I stop it?

Thanks in advance for any replies.
