I have flown two missions in this past week and both have elevation errors. It is just creating either a dome or depression out of the entire map. The first I thought was just an issue because I had a battery swap and maybe something got funky. The second was all flown on one battery. You can view it here. Both were flown with iPad Air 2 using a Mavic Pro.
