I have the vision 2 + and when i try to get a live view picture nothing happens, everything stays black...
i can move the camera, i can adjust everything, take pictures, but i cant see anything.
i have this camera for 6 months or so, and this never happened before!

This has happened to me a couple of times. Had to remove and than download the app into my phone. Also make sure the app has permission to access your photos.

hm did not work out for me.. re installed it.. black..

tried it on my ipad .. same issue..
