So your testing was that it took 3 minutes, but that seems speedy enough to you. Surely you can understand that 3 minutes is unacceptably slow for various use cases? So saying it seems fine to you is kind of silly.
Why would you ever need to do something that isn’t exactly my use case?
Not if Twitch doesn’t fix it, but I think it’s far more likely that things will continue to get worse, rather than better.
