I have a responsive site built in Muse (smithshaper.com) and am using the Carousel Widget 1.0 and it is working fine for desktops (plays 4 videos). However, users on mobile/iPads cannot play the videos. They do see the video player and images but nothing happens when they press play. Other video widgets are working fine for mobile on different pages of my site. The video carousel does play in the MUSE mobile preview tool. I also received the following warning error 66 times after publishing: Web Widget 'Carousel Video Gallery (1.0) - Controller' on page 'HOW TO' is still using the default value of ' ' for 'Custom Play Button' option. Use the Widget Option UI to change this to something appropriate for your website.
