I should have known better!
I should have known better than to spend money on the premium add-on for an app that hasn't had any reviews in 2 years, with many of those old reviewers complaining they paid for premium but didn't get the premium functionality. That's exactly what happened to me - I bought the premium add-on so I would have the Apple Watch functionality. Apple knows I paid (I received the receipt from them) but the app does not and the Apple Watch functionality isn't there. I've reinstalled the app multiple times on both devices and have rebooted both of them many times. So that's $4 down the drain that I spent for functionality that would be very useful if it existed, but it does not. I have contacted the developer but haven't yet received a reply. I will gladly update this review and award 5 stars if I ever get the premium SkyORB functionality I paid for. (Several 2021 updates to the app claim to have dealt with this problem but they haven't.)
