I have been a Beta Tester since mid December 2015 and due to an error updating to what I thought was the latest beta version now have the trial version which does not allow filming unless I wish to pay. Have contacted Neil to be told that no further links can be forwarded and if I do not wish to pay there is a 2 month wait before any more will be released. I get the impression that now the app is now marketable beta testers who have risked their own equipment are expected to pay contrary to the message given out in December,..............Found this in the Inspire forum. GREAT NEWS !!!
Vertical Studio - Looking for Beta Testers | DJI Inspire Forums
Have applied, but just to clarify, once beta is over, do we get the app you sell for free, or do we still have to purchase...!
If you want testers, then you have to give something back at the end of it as well... 
Hi Kevin,
Thanks for signing up for the Beta! Who said anything about charging you guys ? This is going to be free for all our beta program members - forever. It seems that this promise is no longer applicable.
