Ability to change Twitch Product ID
One thing that always confused me as an affiliate is that you can change your emote prefix with a username change but it is impossible to change your product ID for your channel which is what your viewers are directed to when they purchase a subscription for you channel. My username has been DataXemnas for 3.5 years but viewers get directed to twitch.tv/products/talhajam when they want to purchase a subscription for my channel. I've contacted support about this before and they say it is absolutely impossible to change it. I find this hard to believe and that this is a big issue considering people may have included personal information in their old username or simply don't want people to know their old username when they became affiliates and it is something permanent that cannot be changed. I don't know why this is so hard for them to change even though I've seen it be done for some streamers and it would benefit and a lot of streamers who have changed their usernames if this was added.
