Just purchased a second hand ipad mini 2 as a dedicated device to my mavic, overall great condition, battery seems to be in good health but it looks like it holding the power not as long as expected, I have played with if connected to DJI GO 4 app for maybe about 20 minutes on full brightness...
I had read here in the forum that the iPad 2 could be used with my Mavic. My iPad:
iPad 2 (Wi-Fi) [Model A1395]
When I try to download and install DJI GO 4 from the App store, I get a message that reads:
"This app is not compatible with your device."
