Have you guys used DJI's Digital Assistant 2 to download DAT files? OMG! What a lame app (I'm trying to be nice here). Where do I begin? 1. When I copy a DAT file it changes the file name from the original flight date to TODAY'S DATE! What's that all about? 2. When I download 3 files at once, as it invites you to do, the copy is only 1 file, and it's not a zip file, it's just ONE DAT file! Makes no sense to me. So I reverted to downloading one at a time. 3. When you copy files to a folder with other DAT files already saved in the folder, you can't see those other DAT files when you select the folder. It's like they aren't there, however after you saved the new DAT file to the folder that looks empty, when you're done saving, all the original files and the new file do appear when viewing with Explorer. 4. The app intermittently loses connection sometimes in the middle of a file transfer, and it's connected directly to my PC with a USB cable. How do you lose connection? It's not the cable, I tried two. This ruins the transfer when this happens. Flakey comes to mind. 5. When I originally loaded Digital Assistant 2 app onto my PC, I loaded it on my primary USER account, like I do with all my applications (a security measure). However, when I boot the Digital Assistant 2 application, it ALWAYS requires me to sign in as ADMINISTRATOR. Why is that? As a result, all copied DAT files can only be saved in ADMINISTRATOR folders, where I have NO APPLICATIONS, which is useless to me. So to use the files I have to actually copy them to a USB drive as ADMINISTRATOR, switch accounts and copy from the USB to my main USER account where I have applications to use the files. Took me a while to figure that out and I can't find any way around this nonsense, other than loading all my application on the ADMIN account also, a second time, just to use with Digital Assistant 2. That's ridiculous, I'm not doing that. Is everyone else noticing this craziness with Digital Assistant 2? And don't get me started on calibrating the OA sensors using this same app, that's also crazy difficult to complete. Dumb, really Dumb app. I love my Phantom 3P, and I'm wanting to love my Phantom 4, but sometimes DJI just drives me nuts. All of this hassle above was experience during my effort to simply prove to DJI I have a serious 50' YOYO effect in my P4, which I've written about in another thread.
