I keep trying to create team names under my organization but no matter what I name the team as or describe it as I get the message “Please check your input values. The team name may already exist or the characters may be invalid.”
I have only one organization and no teams (other than “owner”) in existence.
It happened to me as well. I tried to create a team in my org called “AMP”. I was successfully able to create it with all lowercase: “amp”. The UX around this could be improved since there is really no guidance provided, no validation until you try to save, and no hint about what’s wrong with the name.
I also had this issue. In case it’s helpful, by inspecting the Network request in chrome dev tools, the error message returned by the request was “group name must be between 3 and 30 characters, and contain only lowercase letters and numbers”
