This wasn’t an assumption. When something has worked one way for years, we know that it’s supposed to work that way. When Twitch doesn’t say anything when changing things, we have no clue that they’ve broken an endpoint for us. Again, it’s extremely obvious that it was always intended to be sorted this way as it was only not sorted this way for literally 2 days out of its entire multi-year existance.
And my main point is that the lack of communication makes developing anything related to Twitch’s endpoints an absolute nightmare.
