Hi,

Would it be possible to upload your flightlog and DAT file for this flight.

In the DAT file tyhe motor RPM are logged, wpil;d be great to see the values  and perhaps the eventlog does have more information about this error

cheers

How long have you had your Mavic Mini?

not long couple days

Hello there zappinbap0. I am sorry to know that you are having these error messages on your DJI Mavic Mini. To ensure a safe flying experience with your DJI Mavic MIni, DJI have added a new safety notification feature on the DJI Mavic Mini in the v01.00.0500 firmware. This new feature lets customers know when propellers need to be inspected or replaced. In addition I will post an official DJI thread with regards to this matter. Thank you.

DJI provides a grace period for refunds.  
Suggest filing a problem report, opening a ticket, to be on record as having a problem right out of box.
If you can't get problem resolved within a few days, before grace period expires, I would suggest looking into returning your drone.
