To change your name, you simply need to tap on your profile picture on the top left of your screen to access your profile, and then tap on your picture one more time. The popup shown after this will allow you to change your name, and you can even choose a different profile avatar from the same screen!
Please note that your name can only be changed once every 24 hours. If you have changed your name within the last 24 hours, you will not be able to change your name until this time is up.
If you want to change your team's name, please make sure you are the team's owner before sending us a message. If you are not the owner of the team, you can always ask the actual owner to consider changing the name and contacting us about it.
