Thanks for getting back so quickly Sanford.
Can you message me on the details of how I'd setup via our own CDN and I can get our dev team to help me.
Aside from the technical questions I'd love to hear whether Twitter lead cards work for you - I've considered it as a tactic but just haven't taken the plunge and actually committed yet.
Twitter is sunsetting the Lead Gen Card on 1/10/2017. It's been down for months already due to a bug on the Twitter side. Now they're shutting it down entirely.
