Not sure if this might be the issue, but after the GO update, did you log in to DJI? ...
Well, Sir, What do I owe you? Is PayPal acceptable? THANK YOU!
As advised, I logged in (no clue ? why that was needed) as instructed and everything seems to work. You are a miracle worker. I used my normal sequence of RC on, A/C on, plug in cable to tablet (window pops up), choose DJI Go "one time only," Model P3A shows correctly, "Enter Camera View." I repeated this twice from the beginning and it appears consistent. Litchi still works, too, after force closing DJIGo. All good it seems.
To answer your previous question now, here is what I have:
DJI GO App 2.4.2 (see note below*);
RC 1.3.20+ (shows a plus sign);
FW 1.4.10
*Note that I had earlier completely uninstalled DJI GO 3.1.6(?) in my frustration and replaced it with the 2.4.2 apk I happened to have on a memory card. When that now opens, it does say "
Update Required" on that first black startup screen (but I learned LONG AGO that the Chinese have the two words, "
required" and "
recommended" very confused.
Anyway, things appear to be okay now because of your help, my friend. You are my hero.
Still gonna learn the ins and outs of Litchi.
