3 missions withou any pictures

Yeas they was fully closed, i tried two ways, using online map pilot, and closing map pilot after taking off and opening DJI Go app, the drone make all the path and take no pictures, i was thinking about my Sd card, actually is a Sandusky ultra a1, u1 class 10. During all fly with Map Pilot the screen didont move with the drone, but on others tests after closing map pilot the DJI go show the full path and drone way. 

I was always near the fly area, because is a small area so RC connection may not the problem, what could make my signal loss for Map Pilot but not to DJI Go ?

this could be any iOS configuration? Should i remove DJI Go Software from IPad and left it only on iphone if i need to take over? 

True one fly came with 1 photo, but i think i pressed de picture button on remote control. I tried with less overlap, i can do it near my home with very less like 60% to test.

Did you try it in a slightly larger area and using a lesser overlap setting? If you are flying super low and with high overlap it is possible there could be issues. Not with the connection but with the minimum distances. 

Also, try the simulator. 

I changed my sd card to a U3 card very much faster, and i've tested near my home using in a very small area, flying higher and with less overlap 80% i think. it worked. i took many pictures and im now trying to mount them on metashape. Thank you! I Think one very importante think is using a very fast sd card on drone.
