What I had to do is:
1: Delete FF6 from my device (ios)
2: Update IOS to current
3: Re-install FF6
4: Update SC3 & Anafi as FF6 commands
Finis. I believe it's a 'Which came first' scenario, whereas a device os update goes public that prompts app designers (Parrot) to follow suit. If you try to update the latest rev app upon an older rev OS, it hangs, because that older OS doesn't accommodate the latest provisions within the app. An alerting statement from the app should & would end that confusion, but Parrot's programmers fail to write that code IMHO. Hope this helps.
