Why is Safety Score not showing up on any drives?

In order for Safety Score to be visible on drives, your vehicle must have Full Self Driving capability but NOT the Full Self Driving beta, and the authorization to the Tesla Account must have been re-established since Tesla's Safety Score Beta was launched.

If you have Full Self Driving but not the FSD Beta and Safety Score is not visible on any of your drives, log out of TezLab and log back in to re-establish the connection to your Tesla account. Once you've re-established your account connection, it may take up to 24 hours for your Safety Scores to be pulled into TezLab. If after 24 hours, your safety scores are still not visible on Drive Details, go for a short drive to prompt a re-sync.
