Tested tpday, first battery no range limit. 2nd battery, max limit at 30x50 m., turning off everything and restart can resume nornal range. 3rd batt same need restart everything.

That is FYI Dji. Another range limit error.
Spark fw .0600 Dji Go 4 for ios  4.1.5 iPhone SE.

Hope you fix this in next f/w

For this issue, just try to restart the APP after you swapped the battery, it should work. Anyway, thanks for bringing this to our attention, we'll forward it to our engineers, will keep improving to optimize it.

Please confirm the following information:
1. Any error message?
2. Did you update all the battery?
3. Did you log in your app account?
Keep us updated, thanks.

1) No error message
2) All battery have been updated
3) Relogin was done.

2 days ago I could fly normally with all three battery. This morning I test flying using 2.4G wifi but did not go beyond 100 m. because the signal became worse abruptly. Brought Spark down, change battery fly again with 5.8G hit max flight limit 50 m. I brought Spark down, turn off Spark, rc, Dji Go 4 and restart everything using same battery I could fly normally. Did this again with 3rd battery, same result, hit range limit, restart everything then can fly normally.

I am ok with this. Restart everything before each flight may be good for such complicated software software. By the way this never happen with .0500 firmware and DJI Go 4.1.3.

And FYI 5.8G is much better than 2.4G. Using 2.4G though the signal quality at take off was very good but signal quality drop rapidly. The area I flown was free of interference. I could fly with 5.8G 200 m.  and still get 3 bars of signal.

Thankyou anyway.

Correction
.0600 firmware flew with DJI Go 4.1.7

.0500 firmware flew with 4.1.5

I will update Dji Go to 4.1.9 and will try again tomorrow

Today I have tried Dji Go 4.1.9 with firmware .0600. No max. range limited yet. Can fly normally by just changing the battery. No reboot required.

Glad you solve the problem. Thanks for your support.

I had this randomly pop up on my 3rd flight/battery of the day yesterday.  I am on the latest firmware (.0600) and DJI Go 4 app versions (4.1.9 iOS).  Each of the batteries were updated when the firmware was released and have all been used multiple times since the update.  To resolve, I turned the AC and RC off and killed the DJI Go 4 app on the phone.  I then turned everything back on and reconnected and everything was good to go.

why dji dont fix that Problem? restarting the app is not a serious solution.

sorry error post

sorry error post

had the same issue. Updating the fw of the particular battery solves this ...

I have from time to time the same messages, but some how I can go further that the limits...

I have the same issue every 3-4 flights. My solution is ONLY to log off from the Go4 app and then log on again.

I wrote "ONLY" because you have to land, connect 3g do "the process" and you are at 70% battery and you never know when it will happen again.

It happened to me even between flights (changing batteries).                                 Ipad mini2 OTG

This happened to me too - I discovered that the WiFi between the RC and iPhone 7+ disconnected but the green light still showed as remained connected to the Spark - if you fly without a mobile device your range will be restricted to these limits so this is why. Go back into your WiFi settings and reconnect the RC to your mobile - no reboot of the RC &/or drone is needed. Once the RC and mobile are linked via WiFi the range restrictions will not apply.
