Finally an new update for IOS. 1.0.54
Installed it and tried out if this time GS works.
And, it does !!

Great to hear it is working for you now.

Good hope other are getting the same results.

I can confirm that GS is not crushing anymore - that is the good thing, but I did not get the FPV back. Still getting a spinning wheel instead of streaming live video. I am starting to think that there something got wrong with the phantom, and that I will have to send it back to DJI for repair before the warranty expires, as I try all the known troubleshooting steps (beside getting 1.0.48 app back) and nothing help getting back the FPV.
