When do you change your DJI drone propellers?

DJI might recommend that change the propellers every 200 flights. I believe  that change propellers every 2000km flight distance makes more sense, not 200 total flights. Sometime, one flight  may only go 1km or less than 1km.   

According to Mavic Air 2 user manual, it states that "make sure all propellers are in good condition before each flight. DO NOT use aged, chipped, or broken propellers. "  How do you recognize "aged" ?   

Any comments and advice?

If I notice scratches or grazes on them but typically ever 200 flights

Hi Professionals,

I've just saw a little video about changing a propeller in Mavic Mini, because I got "ESC beeping" for rear LEFT propeller. I don't see anything on it, it's like brand new (I using this drone around 3 weeks now)
I saw the props should flip around its center... now I checked the props of mine on the Mini and found one of my rear RIGHT prop is tight. Not moving around its center.
I unpacked the screwdriver from its original bag and loosened the screw of that prop a bit....it seemd that screw was "glued" it "popped" a bit when I loosened the prop. Now the prop is moving as good as the others.

The question is:
That "glue" -or something- has been released...should I change the whole prop set, should I change only that screw or can I still use that propeller? (what was loosened a bit)

....a going to change the rear left prop pair because of that  "ESC BEEPING"  error after the flight. I hope I can find out the force I should screw those thin stuff.

(sorry for my English)

Thank you for Your help in Advance.

Is this the same for all DJI drones?

Need to be more mindful of folding props I'd say but generally yes although the Mini uses screw down props so check them very regularly.

No redundancy for losing any props mate - your quad will come down if that ever happens no matter what tech it has

Yeah, gotta take care of those props buddy

At any pre-flight inspection where I find any sign of damage.  (Quite rarely, in fact)

quick deploy emergency parachutes work well for saving drones, for such bad day events,
some commercial contract work where your flying over people requires them as a safety feature like prop guards.
