The question I have is in the DJI go app under settings clear cache I see clear firmware cache. I do not believe I have seen this in the past and if I did the firmware cache was empty. But now it says firmware cache has the amount of 28m. Also if I go to clear it I get  message asking if I am sure I want to clear firmware installation cache. If anyone has any information about this please share.
