Both apps (Kindle and Wattpad) should not require any configuration; they should work out of the box with pgdn's default configuration, which maps the Left/Right keys to Dpad Left and Dpad Right. You probably need to disable the apps' “Use volume keys” options, though. Could you please try whether this works for you?
