Sorry you're having trouble.
Which firmware are you using with the phantom 3 pro?
If this is the first time you are trying to use it it's unfortunate because DJI has made it difficult with their changes in the firmware we can't do much about. We've spoken with them about it and they are working on fixes.
DJI also does not give us a good way to detect firmware so the best we can do is make sure the methods we need actually function as expected.
I'd like to figure out what is the issue you're having. We have hundreds of people flying now and after an initial firmware update nobody has had blocking issues. If you'd like to email firstname.lastname@example.org I can try to help a bit more.
