Due to an inadvertent tap of the 'Update' button in the middle of shooting a live event this morning, the DJI Fly 1.7.0 version on my RC Pro updated to 1.7.4. Upon trying to take off with the Mavic 3 again, the app crashed every few seconds. Tried the Air2S, same thing. No big deal, I thought I would just reinstall the app. Downloaded it from DJI, installed again, same result. No big deal, I thought I would just revert to the previous version. Went to the DJI Fly download page, clicked 'download previous version' and the link took me to a QR code for the iOS version. Cool, so I found a mirror site that had Android 1.7.0 and downloaded it. Attempted to install and got 'app not installed'. Excellent. After 45 minutes of screwing around (instead of filming the live event) I ran across a YouTube video and that finally got me up and running. Here is the fix if you are in my situation (hopefully it was just my dumb luck on my install, but I doubt it):
1. On the RC pro, click settings and then Apps (sorry the wording is not exact but I don't have it in front of me.)
2. Find the DJI Fly app. Click the 3 dots in the upper right corner and then 'Uninstall updates'.
3. It will ask you if you want to revert it back to factory defaults. Say Yes.
4. It will uninstall and reinstall the 1.6 version that came with the controller.
5. Now go download 1.7.0 (the latest version that actually works). This is the link I used: Download DJI Fly 1.7.0 for Android | Uptodown.com
6. Install the APK and go fly again. The Mavic 3 and the Air2S worked perfectly.
Hopefully these steps will help someone that wants to revert to a previous version of DJI Fly on the RC Pro. Maybe there is a better way, but this was the only method that actually worked for me.
