I can find my last position I flew my drone just by going to the DJI app, profiles, and find my drone. Try it and see if it works for you too. I know the drone is not there because I have it in my possession. But I can see the last place it flew with a direct line from my phone's location to the drone. I use my phone or in your case, your controller should do the same. Should work whether there is a connection or not, or the drone's battery is dead or not. At that point you can also click on it to get the last pictures taken by your drone to get a clue where it is. If lost, it may be possible that in your advanced settings, you were set to descend upon losing contact with the drone. You should always set it to RTH. A firmware update can change that so check it each time before you fly. The find my drone video will show how you crashed, like for example, you crash into a tree, or descend into a tree, brush or the ground etc. In any case, once you get to the drone using the find my drone feature, you should look in trees, brush etc. It can be up to maybe 20 yards away too. You'll know when you're close because the dot and triangle will go in circles around each other. Best of luck.
