I'm on Unraid 6.11.5. I've purchased a pro license just now as my Trial will be expiring. Received the email about inputting the URL for the key by going to Tools -> Registration -> Install Key field in the webgui.
I do not see this option when navigating in my Unraid instance. I also tried clicking on Purchase Key/Redeem Activation Code but am getting "..may already have a key or it has been blacklisted" and I am unable to proceed any further.
In the Unraid GUI, it still says i'm on a Trial license.
Any help, much appreciated! (I've sent an email to support as well)
