Known Issue
Disconnecting the auto throttle during final approach has been causing some issues with erroneous uncommanded throttle movement, please note disconnecting the autothrottle isn't required, the auto throttle will go to idle just before touchdown and then disconnect. This will be resolved eventually, if you have any further information on what could be causing this please reach out on the discord channel.
