Your better off canceling your Acorn TV subscription with Roku and signing up directly from Acorn TV.

Hi @LEDksd! We see you're looking to upgrade your Acorn TV subscription. Certain channel providers don't make this option to upgrade available through the application. The best step to take to upgrade is to get in touch with Acorn TV support directly for them to help out. You can reach out to them at https://acorn.tv/contactus/.
