Thanks for searching for the answer you need here!
Just to make sure that we're on the same page - you canceled the Premium Family plan and still couldn't activate individual Premium with the student discount, right? If you've also tried it with an incognito browser or a different device, as @Petya and @Ivan suggested, then could you send us screenshots of the page you get stuck and the subscription section in your account overview? You can use the Insert Photo option in the post editor, just make sure to hide any private or sensitive info. Once we have these we'll be happy to take a closer look.
Keep us posted. We're always one reply away.
