Workstations with creative cloud device licenses start asking for login information, running the license tool fixes some, but not all.

I have a journalism lab that is running all iMacs. OS is current version, updates run automatically. I have Creative Cloud installed on all 8 using device licenses. The device license doesn't require a login to work, but sometimes it stops working this way and starts requiring a login to open the apps. I've created a separate license installer using the deployment tool that will reset the license to a device license. This works for a time, but eventually fails again. Re-running the license tool works for a time, but eventually, even that stops fixing the problem.

Logging into adobe cloud as a user then associates that workstation with the user's account, not what I want.

I need to figure out what's causing the licensing to fail and require a login.
