Air 2s Issues

I am getting interested in 3D modeling. For now, I'm just interested in playing with the process, but I hope that I may be able to do some mapping for local inspectors since I'm tied into the realtor community. I have an Air 2s, and when I tried to run my first pre-flight checklist, I got an error stating that the camera failed and I should restart the drone. I have a high quality SD card (I use my drone to shoot exterior shots of homes) and I know it's formatted correctly. I tried turning the drone off and on again, and I removed the SD card several times. Also, I get an error stating that I need to change my settings to multiple flight mode within the DJI Go settings. I don't have DJI Go and would rather not have to get another app if I don't have to. Is DJI Go required to use DroneDeploy?
