The database feed -- subscribers' lists, who opened the email campaign, list of past and pending email campaigns, and so forth -- are no longer viewable from a Nook tablet. They worked fine before the recent CC changes.
I take a Nook tablet when I travel because it is smaller and much lighter in weight than a laptop, it can be kept in a suitcase when passing through TSA screening at airports, its internet connectivity and browser is far better than iPhone or iPad when traveling overseas, it has a larger, easier to read screen than iPhone, besides its original purpose of being an e-reader.
What changed that has made it impossible to manage CC from a Nook tablet? I can no longer manage CC when traveling unless I carry a laptop or use the tiny screen on a smart phone.
