App Crashes won't install – FreeFlight Mini Review

I have downloaded the app numerous times. Each time, I can 'accept' the terms and 'allow' the app to access photos. After that it crashes and then closes. Tried on 2 different iPhone SE's and an iPad Mini 2. All the same result. Have powered off the phones and reinstalled. Still no luck.
