Hi there. If you are trying to enter the same name as your Xbox gamertag, it is likely triggering the automatic filter as a violation of rule #6 of the Code of Conduct, due to the last two digits. Try using a different name. If nothing happens when you save, switch to the mobile app. Please see Bungie's [url=https://help.bungie.net/hc/en-us/articles/7648312251284-Bungie-Name-Guide?_ga=2.203020824.889820463.1660081325-556190839.1657624416]Name Change Guide[/url] for additional information on Bungie Name changes.
