Is there a cap to number of entries in a Form?

I have been using Forms in Smartsheet for a number of years, and my team is constantly changing or adding questions we ask while we use the Form. However recently, when I add a new Question to the Form, it shows on the backend, but when I preview it for functionality, the question is not showing up at all (no logic added yet). So is there a cap to how many questions can be added to a form?
