Troubleshooting

Fix something that broke

An invite never arrived, a change did not stick, or the permissions screen looks wrong — diagnose it here.

Check the account you are in and whether the invite is still valid

Two things cause most YouTube permission problems. The first is being in the wrong account context: channel permissions live on the Google Account, and if you manage several channels you can easily be acting as the wrong one. The second is invitation timing — a channel-permissions invite expires if it is not accepted in time (about 30 days), so a "missing" collaborator is often just an invite that lapsed.

It is worth repeating the core rule, because it prevents wrong turns: channel permissions work on every channel, personal and Brand Account alike. Access is not the Brand-Account-only part — only ownership (a backup owner, a transfer) requires a Brand Account. So if you can add a manager but cannot hand over ownership, that is expected behaviour, not a bug.

YouTube access problems — common questions

The invite most likely expired — channel-permissions invitations lapse if not accepted within about 30 days. Confirm they opened it with the correct Google Account, then re-send the invitation and have them accept it promptly.
