From my understanding, the camera can't read some SD Cards (The manual isn't specific on which ones work and the ones that don't, but it's specific that the camera can support cards up to 32GB.). Also, the big problem is a MAJOR bug with the Vision app. DJI hasn't released an update with a fix for it. The bug with the app is this: You know when you download apps like Instagram that ask for access to your phone's photos? The Vision app is supposed to do that, but the bug makes it not ask for camera access for some reason. I hope this helped solve the problem.
