Possible solution to YouTubeTV
HARDWARE: Synology NAS, with Channels Apps (not Channels docker)
Like everyone else, I was being blocked by Google/YoutubeTV. Here is what I found.
Step 1: Create a new Google account. (NO Passkey or 2FA.) Just the username and password. PW has no special characters, just numbers, and letters (upper and lower case)
Step 2: Do NOT subscribe to YouTubeTV, yet.
Step 3: Sources--> Add Source-->TV Everywhere. Add the new Google account.
Step 4: Channels will try to connect. It added the basic free channels. (ABC News, CBS News, etc)
Step 5: Once completed, THEN I purchased a NEW YouTubeTV subscription. (Trial discount).
NOTE: I tried to use my existing YouTubeTV account, but it did not work.
Step 6 Once the NEW YoutubeTV has been set up with the NEW Gmail account, then return to CHANNEL--> SOURCE --> MANAGE (youtubeTV)-->RESCAN CHANNELS. It adds the eligible Channels (Note: TVLand, CMT, etc are missing)
When I set up the NEW YouTubeTV subscription, for LOCATION, I used a zip code in Montana and ran ExpressVPN/Seattle on my Apple TV. I can get the local channels on the YouTubeTV App in Montana. Just make sure your VPN is on your device. On the Channels App, the local channels are my home local channels. Hope this helps. This worked for me.
