I've found you can set a distance limit at 5000m instead of just leaving it at the default of 0 in the Phantom settings as well. Probably not the best way to do it though. Logging in and out of the app is the better fix.
Spark, Mavic, Phantom 4 & Inspire 2 all which get used regularly :) fortunate to work at Ace Company so get to use the demo models. And have 3 Racing drones of my own
