I have seen some other threads about this issue but they didn't seem to replicate what I am running into so I thought I would create my own.
Anyway, I just moved my Channels DVR service over to a RPI 4 and I noticed that in scanning the TVE channels I am not getting FS1 or 2. In the log is says "2020/03/21 11:57:37.962330 [TVE] Channel scan 130/201 FS1 failed: notAuthorized
2020/03/21 11:57:38.016840 [TVE] Channel scan 131/201 FS2 failed: notAuthorized".
However, using the login directly on the Fox Sports page it works fine. I am also able to view them in the Youtube TV app. Oh yeah, I am using the Youtube TV service.
I have re-scanned at least 6 times over the past 3 days.
Let me know if you need anything else, full log or whatever.
