I'll try to be polite.
Maxon licence management is one of the worst, if not the worst in the industry right now.
I personally, and everybody in my studio has problems with maxon licensing all the time.
With every iteration of this system, Maxon is trying as hard as it can to make harder and harder to unasign and assign licenses.
Now it takes like a 20 clicks with typing passwords on the way to assign license.
Today, I cant even log into your system. I have to deliver something today for my client, an I can't even open Cinema 4d because of someones greed. This behavior will not lead to anything positive for your company in the long term.
Edit.
Ok, I saw email from Maxon considering today's maintenance , but every other thing still applies.
