Apple ios lightening to HDMI adapter does not work

Date 09/04/15

Purchased Apple ios lightening to HDMI adapter for a presentation. The adapter did not work either with my iPhone 6 or Air Pad 2. But the adapter did work with an older iPad. Please fix the problem. This is my second request for help on this issue. My Apple ID is fultonck@yahoo.com and my iPhone 817-791-4425.
