Layar app is an open platform and sometimes it can happen that the same or similar page is augmented in several campaigns. In the current Layar App version, a list of campaigns that have augments on top of the same page will be shown first after the visual search ("Tap to View" function). Users can choose which campaign they would like to see from the results and launch the campaign separately. Users will not see augments from other campaigns while they are viewing your campaign.
Please note that Pro campaign are prioritised over the basic ones.
