No Sound on iPhone 17 Pro Max

I have faithfully used this app for more than three or four years up until I got my iPhone 17 Pro Max about a year or so ago. Unfortunately, while the 40 Hz light works, no matter what I try I cannot get the 40 Hz sound to work. Other than that, I have really loved this app in the past.

Great

So helpful for memory

So many issues with books

Page numbers in books are all messed up. If you record the page number to pick up your reading tomorrow, that page number will, like as not, put you back to what you read yesterday! Why can’t the app open today with the last page from yesterday? Very frustrating.

Editing is horrible with spelling mistakes and occasional indecipherable ‘letter salad’. But it is the best I have found, so far.
