Just saw a tip over at the DJI forums that actually works. Note: You MUST have a rooted phone for this hack to work.
1. Download and install the "Disable Service" app at: Disable Service - Android Apps on Google Play
2. Start the app and select the DJI Go/DJI Go 4 app in the list of third party apps.
3. Remove the check mark next to "MapService".
The next time you start DJI Go/DJI Go 4, you will have Google Maps back!
