Why do I see an "invalid meeting ID" error message?
If you are trying to join a session and encounter "The training ID is invalid" message, it means that the training ID you entered does not match with the session you are trying to join because it is incorrect, was mistyped, or the training ID has expired.
You might have entered it wrong.
First, try re-entering the 9-digit GoToTraining ID to see if you might have made a typo.
You might have the wrong meeting ID.
It's possible that the GoToTraining ID you have is incorrect. Try contacting the organizer who invited you to the training and asking for the correct GoToTraining ID.
The meeting might be expired.
The meeting ID might be from a past GoToTraining that already expired. Try contacting the organizer who invited you to the GoToTraining and asking if there is an updated session you can attend.
