In essence, presentation mode should allow a single tab/click to got to the next page, and a double tap/click to go back (this applies to both the free and paid versions). In practice, the next page functionality is lost when zoomed in.
I have created an internal bug report for this, and in the future should an update be needed, please ask here or about this number:
RT#4508: Presentation Mode next page
I apologize for any inconvenience while we work to resolve this.
