Embedded iframe code for Scheduler isn't mobile friendly?

[RRC]

When adding the iframe code to our website (Squarespace) it appears fine on desktop but doesn't seem to be mobile-friendly. It doesn't stack like it's supposed to on mobile. So all you see as a user is monthly view calendar and when you click on a date it doesn't dropdown/pull up the times to choose from. They stay to the right - off of the mobile view and you can't scroll to the right to see them. Shouldn't the iframe option work on mobile  just like it does if you were to click the Zoom Scheduler link on mobile?
