Rise in Moodle on iOS - can't scroll to bottom

There seems to be a partial workaround for this issue which I just discovered.  In Rise, you can add 100px padding to the bottom of all Continue buttons.  This will push the button up to where it can be accessed on both Chrome and Safari browsers.

However, this isn't a full fix, as when you review lessons that have been completed you cannot scroll down to the gray bar that allows the user to advance to the next lesson.
