This was exactly the first thing I tried. Also alternatively tried URL buttons with "navto://relative/next".
UPDATE: I've tried both above methods with Acrobat on iOS 9 device. Same thing - buttons are clickable, but don't change pages
There must be something wrong with my export settings??
Navto is for DPS, not PDF!
Let's see a screen shot of your buttons and forms panel with one of the buttons selected.
All of that said, interactive PDF is a crapshoot especially on mobile devices: It's okay to say no to interactive PDF | BobLevine.us
"Przycisk" stands for "Button" and it has two actions:
1. Go To Next Page
2. Go To URL navto://relative/current#next
This Adobe article says navto://relative urls are supported by all mobile platforms in PDF.
Navto does not work with PDF. Perhaps a translation issue? It's DPS only.
Secondly, in English, the event should be on tap or release. Not sure what that says in Polish.
Does it work on the desktop?
Have you tried a different PDF reader?
These things on mobile are complete crapshoot.
Yes, Bob, it works perfectly on the desktop. Id does not work on any mobile platform via Adobe Reader. But I tried it on iOS 9 with Foxit PDF (which returned "Not supported operation" error when tapping on buttons) and Tiny PDF, where buttons worked OK.
This is genuinely weird. All I want is a simple next/previous, first/last page navigation. Nothing fancy.
There's nothing weird about it to me. Interactive PDF is nothing but a crapshoot on mobile.
That's why I wrote the blog post I mentioned earlier.
This is not an InDesign issue. You might want to pop over to the Acrobat or Reader forums and see what the gurus over there have to say.
