Hello, how do you change your username? I tried multiple solutions didin't help. It's imposible to reach out for a support So I'll just ask here. As a streamer I need to change my username to recieve donations

Got family tomorrow so probably won't log on much over the weekend.

Yeah, understandable. I came back with the answer. Twitter support actually helped me and thank you very much for mentioning it. 

And there's a thing I got few donations but my money is on hold, probably because of a new account
