Under Advanced settings...Changing EXP...How to save it?

[grtday]

Just saw Bill Nichols video on how to fly and shoot more smoothly.
Went to DJI Go 4, opened the main controller settings opened the advanced settings for the bird. Went to Gain and Expo tuning.
Opened EXP and reset all 3 screens (throttle up, rudder right, and forward/right) to .35. Entered return and Completed/Done and returned to main screen.
When I came back to those settings, they had all returned to .50 which seems to be their default.

HOW do I save those settings in my DJI P4 V2 remote?

Big thanks to all of you experts!

That sounds like you did not have the drone connected to the app?
Any settings that are stored in the Phantom, need to have the Phantom connected when you change them.

Y'all are awesome.
Precise diagnosis. Bird not connected.
I shall retry!
Big thanks to the mighty Meta4!
