When I take a picture with the drone, it makes the shutter sound and appears to take a picture. When I try video, it changes to say "recording", and a timer starts ticking upwards. But nothing ever appears in the gallery. I am referring to the gallery in the Tello app. I tap the triangle play sign, but both the video and pictures section are always empty. What am I doing wrong? I have tried 2 different phones, both Android 7.0, and no luck at all! Please help!
