Has anybody got the old DJI GO 4.1.16.ipa
I have updated to the 20 version and now I can not fly anymore with the otg cable.
The wifi connection in europe is so bad, that we need the otg cable.
What I understand is that DJI does not want to fix this problem, they say the wifi connection is much more stable, well we all know that is lie!

With iOS your stuck, sorry - when Apple isn’t slowing your phone, they make side loading apps nearly impossible.  

You might try a 3rd party app from the play store- I use ‘VR Pro’ it’s free to try

I think on 4.1.20 you are better flying WiFi and WiFi is working well. Dansmart is the local forum naysayer he would have you think you could never fly again.

Think you will find on this thread dansmart is using a different option.
