Yesterday, I got the Unity Hub 1.5.0 update. A few hours later, in the middle of working with Unity, I suddenly got a license error. Tried to re-activate using my PS4-serial (which I had used before, but just for a few days recently). Got an error; tried to re-activate with my Unity Plus subscription serial, got another error (both were "server errors", I still have one activation free on my Unity Plus serial, can't check the PS4-serial). Thought it was probably just some temporary error and went to sleep - just to see the same issue again today. Error message that I see right now: "License server return unknown error. Please contact email@example.com for more information." There was also an error message about the license server being down before (I didn't write down the exact wording). That one had a link to Unity Cloud System Status Page - but that shows "license" as "operational". So, I have two valid licenses and cannot work with Unity. That is not cool.
