Yes, we made a change to make the page navigation nicer for embedded reports. We got feedback that the page tabs don't look right when they're embedded in iFrames in blogs or websites. The pages are still available if you click on the '1 of N' option. We're working on some additional improvements to make the page navigation better as well - you'll be able to set the page that loads when the iframe loads (instead of whatever was saved in the report) and you'll be able to programmatically set the page. This means you'll eventually be able to create your own page navigation buttons. Lastly, we're looking at a better overall design for page navigation when embedded in publish to web - the tabs at the bottom were seen by many as out of place. Suggestions are welcome - we're thinking to put the page navigation UI at the top of the report or on the sides. Any ideas you have for how the page nav should work would be appreciated.
