Activation manager now works …but…?

My Activation Manager has never worked so I registered Cubase off line and it works fine. I also registered Amped Electra which somehow deregistered itself and stopped working.
I put a ticket in to Steinberg and eventually they replied that I should open the activation manager and activate Amped Electra again.

Just as an experiment, as Windows 10 has had an update, I tried running Activation Manager on my PC and it works! I’m All products, I can Cubase as activated but nothing else.
I was about to sign in but I got the message “Attention: Discard offline licences.”
That made me worry that signing in would discard my Cubase 12 licence as that was made offline. What should I do?
