it's different for everyone depending on your provider as some have full service, some intermittent others not so much at all, the acid test will be under-load when the games start.
example, our firestick wasn't affected & has cleared whenever I have tried it (assume it uses no xc code in providers own app) but our E2 systems (running sly c/s, vm c/s & IPTV services) borked up when I tried to refresh the IPTV side, provider kept me informed & service returned quickly, others with the same devices are still waiting for a stable service to return so the devices are still capable of clearing channels which points the finger of knowledge at providers to get people back up.
