How to enter a new license key in Cleaner 7

I’ve just purchased another year’s Cleaner Professional through Amazon as it was a better deal than just auto renewing. I have an existing license for Professional which will expire shortly. How do I enter a new license key in Ccleaner 7 as if I go to my subscription there’s no option to do it? Thanks.

Hi @Iandswift,
I have sent you a DM for more details on your new license so I can advise you further on this issue.
