On our Facebook page, the list we would like to save all contacts generated from the app is not available in the "Select a List" drop down menu.
In addition, attempting to make almost any edit to the app results in a "We lost connection to Constant Contact Join My List App, please refresh the page."
I am sorry to hear that you are having issues with the Facebook app. Can you try logging in with a different browser and see if that helps the connection issue and the list selection issue? If you continue to have issues it would be best to call into our support team to work with our specialized team that works with this app.
