I am sorry to hear that the new user experience is giving you some weird quirks. I want to try and help you troubleshoot some of these quirks to see if we can make Constant Contact great for you again. I would like to know what browsers you have been trying and if you have used any safe modes within the browser.
As for the features that you can no longer find, what are they so we can help you navigate to those again?
Our Social Share was down most of last week. The good news is, it has been fixed! You should now be able to post to Facebook normally again without error.
Thank you for your question. I do apologize but there is no way to revert back to the old interface. However, we understand there were certain features on the old interface that are not available currently. I will be happy to pass your inquiries along as feedback to our product teams.
I also encourage you to post this and any additional feedback you might have about the new interface in our Feedback forum.
