Why when i use DJI goggles with Spark i get only 50 meters range?
and there is no option to change that.

Distance limit is imposed by lack of DJI GO 4 app....connect your phone via WiFi, then use the OTG cable to connect to the goggles.

Odd thing though, between flights, after changing battery, distance will be limited unless you unplug the OTG cable from the RC (at the RC end) and then plug back in.

This range bug persists even now that the goggles are officially supported.  Must unplug the gogs and boot up in DJI GO 4 to approve the flight before connecting.
