Two fatal issues I discovered:
- the apple store was so biased, even when I typed in "piano tabs", it couldn't find your app in the top 10 results. I had to type in the name of the entire app: "Piano Tabs: Learn & Practice"
Then I attempted to install it and got this: - "This application requires iOS 15.0 or later". This is a deal breaker on so many apps. I don't trust apple enough to change my iOS version. Note: this happened on a pretty recent iphone 7+
