I recently took over a rather large project to help someone out of a jam.

They have 100+ pages of .html for a presentation. I added swipe and some other things they were having problems with. Everything runs fine on all devices. However the company has an 'App launcher' theybuilt and I was told everything runs inside an iframe. I tested it on their side, and once they load the "app" I helped with the swipe doesn't transition smoothly, and on some screens it out and out shutters and stops.)
