I have found how to roll back the DJI app to an early version so that I can restore Google Maps. My question is- should I also downgrade my RC firmware to an earlier version or would the the current version 3.1.0 (7) be compatible with the older DJI app version 2.8.xx ?
Yep, running dji go-2.8 firmware- 1.9.60 with RC-1.60
If you want to downgrade look over at phantom pilots, msinger who is a genius, posted a great "how to downgraded firmware"
