username

The Android app doesn't appear to have the option, so iOS may not either. You can do it on the website.

Are you entering the right password when attempting the change? 

So it’s your phone not the server

do you not own a computer? 

Ok, I have a simple trick. So go to your messages through the app and find a link to a club you are in. Maybe a news post , because those appear in messages. Then click it, and then the news post will come up. Since the app does not support clubs, what you are seeing is a form of the website. You are actually using your app as a browser now. That’s why you had to find a link in your messages.

So once what you see looks like a browser, simply do what you need to do and click the buttons to change your username like you would on safari. This is kinda confusing so if you don’t understand or have questions contact me and I can give you a more step by step process. Let me know if it works.

Also you aren’t allowed to change your username more than once and you also have to activate your account if you haven’t alteady

If you already changed your username the page will reset and it will give an error message. Maybe that’s what happened

I’m on an iPad, it’s the same thing as what @ABlazingBishop said, go to tournaments<daily, and you should be in a web browser sort of thing.

No problem
