I have not tried other apps to see if the same thing happens, but a card with an Audible.com link to a book created in a browser on my iphone opens again in the browser on the iphone, but opens the Audible app if I use the link on my iPad. If I create a card with the same link from the browser on the iPad, it still opens the Audible app, which is NOT what I want. Does anyone know why this might happen? Thanks!
