Great app. Though, a few issues. Opening links that I previously saved in order to come back to a particular principle sometimes takes me to a random one instead of the one I intended. Also, I have never gotten the 'Ask Coach' feature to work...It just loads continually. Otherwise, absolutely great content & good app.

The app is quite mediocre, however, the content is gold 🥇. Thank you Ray for making it public and accessable for all.
