Slow flight speed

Hello

I just switched to Map Pilot for DJI - Business for mapping, the main reason is that I will use the Mavic Enterprise Duo drones. I have now a Mavic Pro 2 drone with latest firmware and made two mission flights using the version 3.1.5 build 041820191 with 80/80 overlap, and the maps are pretty good, but the flight speed between pictures is very slow, 1.5 m/s, even when the drone reaches a boundary and turns back.

In the second flight I double checked the max speed user setting (15 m/s) and the calculated speed is 4.3 m/s, also the SD card is 2 sec/image according to my SD.

It takes more than twice the time to do the same mission flight than with the other app I used before.  

Note: First flight was at 6 PM at 50 mts. (164 ft.) no much light, but the map was OK, and the second flight was in the morning with better light conditions at 70 mts. (229 ft.), but both had the same speed of 1.5 m/s.

I don’t know if I am doing something wrong, or maybe a drone/camera/app setting is wrong, please advise.

Thanks.
