@TeamYouTube My custom channel URL is.... odd. I changed it years ago to a new one, which worked, but the old one still works too but not on mobile (desktop only) and my Dashboard still links to the old one. How do fix?
Depending on when your channel was created, it may have a username. Usernames are no longer required today, but you can still use this URL to direct to your channel — even if your channel name has changed since you chose your username. More: https://yt.be/help/LYia
