Molto bella e Buon Lavoro

Almost 3 years later from when this post was created and this is still an issue. My prefix is "x1upca1". Not only did I get an extra 1 at the end instead of a "d", but I also got a random "x" added to the beginning and had no way around this when I had changed my username years ago. Twitch needs to provide more flexibility on this. Partners can pick any prefix they want. Why not give Affiliates the ability to choose with a minimum of 6 characters, then use a check to make sure there's no duplicate. Seems like the simplest and most common way to implement a way to not have randomly generated prefixes and in my case doesn't match very well to my username 1upCAD.

I wish they would at least offer some to choose from, and no numbers.

the prefix must be the same as the channel name

I think it's need to be free change at the first time, and don't auto generate number.

When I reached affiliate status I didn't even get anything similar to my username, they gave me twitch3988. Like this does not match my username in the slightest. I changed my username to see if maybe it was bugged and it still gave me twitch with random numbers.

I want the number to match the one in my pseudo...

I want to remove the number

No idea why there's a random "66" on mine.

I can see the Partner benefit being great to choose your own prefix, but can we at least choose different characters for those 2 random numbers?

Meaningless random added number is very annoying.

This is very true. I recently added my emot for the first time it is just horribly butchered.
