らんちゃんWe have expanded language support for YouTube handles. We plan to update your automatically assigned handle to better reflect your current channel name starting in 30 days. If you do not want an automatically assigned handle, please update your handle now. Your handle will appear in places like comments, Shorts, and mentions. UPDATE YOUR HANDLE Handles can be changed at any time. Keep in mind that handles are unique to each channel, so once a handle has been chosen, it can’t be selected by anyone else. Thanks, The YouTube team
