Free upgrade to ZimaOS+ not working

I’m upgrading from ZimaOS 1.4.x to 1.6.x on my Beelink ME Pro with 5 drives and it wants to charge me for the “free upgrade”? Can you help? and thank you!

Same here. I dont get the upgrade in my settings? What to do?

you can get an activation code after you send the screenshots of your settings panel(General tab) to this email address: community@icewhale.org.
