I am getting blocked now from channels I have been able to view before on my mini. There is a new pop-up which says “the root CA certificate has been replaced.please download it again and install”. I suspect auto update has updated to system version 1.2.7 as I am not having this issue with my Air on 1.2.6. Any suggestions to unblock channels, and how do I download a root CA certificate and install? Thx.
