I am currently running a GS7 edge with android 7.0, so easily fit the required specification stated in your blurb, yet the app does not work anymore. I have been on the phone to support, but basically I'm being told it's my problem and nothing they can do.
N‌ow the way I see it, I have an expensive subscription (with additional Pooleys Plates), for something that has been sold to me and now doesn't work. I still need to go flying and currently I'm using a trial period on a Garmin app. Now do I need to complain to a higher power about this, because I am NOT getting what I paid for at the moment. I feel like I am being ignored here and that is just not good enough. Fix it or give me my money back and I will go elsewhere, where things actually work!
