I have a V35 ThinQ, which is basically a G7 in a different chassis. I was able to connect with the app and the MM long enough to update the firmware. After that the app opens, then crashes every time the drone connects. I tried changing the USB connection options, restarting the phone, airplane mode, and reinstalling the app, all with the same result.
I did get the app to work with the MM on my old S7 active. So far it works great with my old phone, but It's not ideal to lug around a 2nd phone for a device that is suppose to be light and portable.
