After an IOS update (26.6) on my Mac I lost all TVE channels. I have rebooted and checked for updates to Channels. I finally (maybe unwisely) deleted the YTTV source and tried to re-add it. I have a separate, non-2FA Google account, (same as for my YTTV). I can log into any channel individually on the web and it works. When I try to add the source back to Channels I get the dreaded Cable Authentication failed. Running this in an up-to-date Chrome Incognito window.
Any advice would be appreciated
