Hi @egr103
When a button does not function as expected, the problem is usually a JS error on the page.
Normally I would ask you to open your console log and report any JS errors you find, but the iPad makes this a bit difficult.
This is an older tutorial, but you can enable developer tools on your iPad like so:

This will allow you to track console log errors.
Let me know what you find
Cheers
