strange notification while flying

[palito]

While flying yesterday, mini4 pro rc2, 3 or 4 times on the rc2 screen appeared the notification- Preparing for takeoff - while Inflight! The notification in flight was replaced by preparing for takeoff. then it went back to inflight. I did nothing, and operation was unaffected as far as i could tell. Freaked me out as drone was 800 meters out over water and mud. Anybody see this before.

That means you need to reinstall the app.

That's simply a false alarm, like the propeller not attached message that I and others have seen while the drone is flying 100% normally.
Those things happen occasionally.
