I received my Mavic pro 2 yesterday from DJI refresh. I noticed that when I push return to home that once it starts to come down the sensors all turn red. I have been with Mavic 2 Pro for 2 years and never ever noticed that. I called and 2 different techs said it's not normal and advised to refresh the software and redo the IMU and Compass but before I did that I called a 3rd time and the girl talked to a Senior Tech who said that is normal when landing. I know in the past that when I was landing sometimes the drone says UNSUITABLE TO LAND. SO there must be something watching out. Also, I noticed that this new unit does not hit the pad. In the past for the most part I've always landed on the pad when return to home is engaged. On the pad or close by give or take 5 or so feet. This drone could be up to 10 plus yards away. I've only flown it twice and it's all good but I am wondering what's up with these 2 things. Please weigh in if you know for sure the answers. Thank You.
