I have an SD card in the spark. But I have the app set to cache video to the phone as well. I notice that only about 50% of the time it will save video or photo to the phone as well. For example, my most recent flight list from today: Screenshot_20180613-020623 by PhotoGD posted Jun 13, 2018 at 2:07 AM Flight at the bottom I took 5 photos but it shows none. And none are in my phone anywhere. However the other 3 flights have correct number of photos and they are saved to my phone. Am I doing something wrong? Its doing the same thing for video... Sometimes it saves and sometimes it doesn't. Its not a storage issue. I have 512gb of storage on the SD card in my phone.
