"Remote Desktop License Issue" error

I wanted to see if any other organizations have been getting a blue error message pop up telling them there is an issue with their Remote Desktop License and that they will be kicked out soon and any new sessions will be restricted to 60 minutes. It started in early October and was fairly rare and sporadic, mostly just 2 to 3 users and only every few days or weeks. But yesterday, all but 1 of our Ticket Office staff got the error and was subsequently kicked out. They can log back in but its very inconvenient if they are in the middle of an order or if we are busy.

Someone from the University's Tessitura Group suggested it might be a citrix issue and I did find an article from their website related to this issue: https://support.citrix.com/article/CTX460004/remote-desktop-license-issue-with-rds-per-device-cals. We haven't had time to test anything out and anything we do test, its hard to tell if the solution sticks because some days we don't see it and others we see it a lot. So if anyone has seen this pop up and found a solution, we'd love to hear about it.
