I have activated new V19 on my MacStudio, but I would like to use one of my V18 license on my iMac, which I have used previously on my MacPro, which is now out of service. There is always the message that the activation limit is reached, but no option to deactivate the license on the MacPro and reactivate it here. Surprisingly, my old licenses (V15, V16) are also listed as V18 licenses...
