A. If the play button is difficult to reach, consider using the 'AssistiveTouch' feature on your iPhone. Go to Settings > Accessibility > Touch > AssistiveTouch, and turn it on. This will create a floating button on your screen that you can customize to include the play/pause function, making it easier to control playback without reaching for the button.

B. Alternatively, check if the app has a landscape mode. Rotating your iPhone to landscape may reposition the play button to a more accessible location on the screen.
