Hi Adam
I am also unable to upgrade my plan, from free version to premium. It keeps saying my card details are not valid but I've double triple checked and they are! I've tried different browsers, cleared browsing histories, and also tried to do it from my phone but it won't work. The bank is closed but I did check and my card isn't locked and seems to be fine for everything else. Please help 😭
@hcfamily Sorry for any trouble.
Check out this thread for more information around the error message you are receiving when upgrading: Error Message: "Sorry, your payment information is not valid"
In the meantime, I have created a ticket with our support team for you.
They will be contacting you privately via email to help look into this further, so please keep an eye out for their message.
Thanks for your patience!
