I am developing an app for a client. They have given me the licence key for their paid plan, however when I paste the licence key in the licence key section under My Account, there is no button to submit the key.
I then went over to the classic editor, pasted the licence key and submitted it their. Got it all working and then went over to the beta editor again. It works now, but would be great to submit the licence key in the beta editor as well.
