Once I have changed my settings how do I save them. Currently I change them then when I go back in they have changed. On sensitivity they are all set on 0 and I cannot change them up, why is this happening.

Is your Mavic powered on and connected to DJI GO? It needs to be in order to view/save most settings.

Hi, we're very sorry for the inconvenience caused. Can you please show us a screenshot of your settings that you are trying to change so we can check it? Also, please make sure that your device is connected to your drone. Thanks.

Sometimes certain settings reset to default with firmware updates. I keep a list of changes that I like to 'set and forget', then after each firmware update, go through and make sure they are still set.
