I was working on my custom on-screen chat overlay which in the console was saying my channel didn't exist even though it was linked with my channel. I thought "oh, maybe it just forgot my ChannelID, that's fine, I'll just relink it."
When I go to reconnect my Youtube account, it takes me to old.7tv which after clicking the app-content div, it asks me to sign in with twitch. after signing in, however, a new window pops up for the auth page, which spits out a route that according to the json page that pops up, doesn't exist (404; see image.) I believe it's because some of the endpoints for login aren't fully up to date(?)
tl;dr https://7tv.io/v3/auth/twitch?old=true doesn't exist anymore, but it's required to login with twitch for YouTube channel integration.
