I found this frustrating also. Now that the product is more mature, Adobe has a DPS help file at https://help.adobe.com/en_US/di…..e_help.pdf

Essentially, you cannot use this feature on a folio made for an iPad. “Certain button actions
Go To Destination, Go To Next Page, Go To Previous Page, Show/Hide Buttons, Sound, and Video button actions are not supported. Multiple actions are not supported. On Click and On Rollover events are not supported.”

It looks like a muti-state object is the way to go for your needs: “Supported hyperlink actions include Go To First Page, Go To Last Page, Go To URL, and Go To Page. Supported slideshow actions include Go To State, Go To Previous State, and Go To Next State.”
