Not give adds to subs!!
I cannot just contact you I am redirected everytime! I am getting pre-rolls and ads on a channel I paied for a three month sub too! This is not the first time. It sucks and does not want to make me buy the twitch sub, to either channels or twitch its self. DO BETTER. You have the ability to see who has subs, it is not unclear, and they should not be a thing for streamers who want them off anyway. I get that it is a business, it is driving away streamers and viewers, more and more competition is building. You want constructive not fixing adds will be your downfall.
So sorry, but you definitely should not be seeing ads on channels you are subscribed to, unless the streamer has chosen to not enable ad-free viewing for their subscribers. If the subscriber does have ad-free viewing enabled, then there's a possibility there might be a bug; and in this case, our support team should be able to help you out with this.
