Looking at the battery settings, the maximum auto discharge time is 5 days. When was this changed? I'm sure last summer I was able to select 10 days.

Hi, TrippleDelta. Thanks for reaching out! Could you confirm your battery's current power percentage when setting the discharge day? Kindly let us know also what's the firmware version of your Mavic 2 and the DJI GO 4. If you could add a screenshot of what you're experiencing, that'll be appreciated.
