I have been using generatepress premium theme for a year already and today I decided to renew to receive all updates and supports. But, once I have paid the money, I received a receipt with a link to download the theme. I already have the theme installed from the last year, do I need to download the new one and install it again on my website?
That email is autogenerated by our system on renewals the same as if it were a new purchase. So no need to download and install the plugin. Your existing plugin will continue to receive updates when available.
