Can't delete old Windows-device from my Apple ID
I have a moment 22...
I tried to activate the new "Advanced Data Protection", but got an error saying I have to first update or delete some old devices from my Apple ID that wasn't supported. I deleted a bunch of old Windows devices (shown because of iCloud), but one is stuck and can't be deleted.
When I click the Windows-device it says "Device Not Found. The device you selected is no longer associated with your account". The other Windows-devices could be deleted without issues, but not this one.
I tried deleting it from my iPhone, iPad and browsers but same error. Not sure what I can do more since the device is recycled >5 years ago and can't activate the new data protection features until this is deleted.
