PubSub twitch.listen can't authenticate properly on broadcast channel

Refreshed manifest, but issue persists.

Something else worth adding is that I am getting CORS errors:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://pubster.twitch.tv/publish. (Reason: CORS request did not succeed).

Two of these every few seconds.

They are regarding these requests.

Somebody in the support discord told me this was unrelated, but I am starting to doubt that!
