Deleting data before sale

Hi , I’ve sold my mavic mini as just not using it since the upgrade but my question is how can I clear the flight data etc for its new owner ? I know a read a previous post on doing this but I cannot find it and I’m sure there was a easy way to do this so any tips most gratefully received. Many thanks , scott

No need to.

The flight data is held against the user logged into DJIFLY

New person logs in as themselves and it starts afresh
