ASC M1 Update, cant remove old pre-M1 Macbook activation from account

[Kilo300]

Hi,
Essentially the M1 update is using 2x the activation slots, and I can't recover the old one
I've updated and re-activated 3 of my products in ASC to M1, but I can't seem to recover the activation from what they think is the old Macbook.
I went to the main website and tried de-activating, but even when the popup sais "device has been removed" It actually isn't and is still taking up an activation slot.
 Anyone else having trouble with this?

Having the absolute same problem. I’m getting no error, but the activations persist. It’s really annoying as it bracket my actual setup after updating, because now my activations are crowded with unused old computers that cannot be deleted.

I would recommend raising a ticket with Arturia. They will be able to deactivate all your authorisations so you can start again.
