One of my clients reached out this week and told me that the projects I developed for them were no longer playing the audio for any slide videos from Vimeo.com. I have notified Adobe of this issue, and they have logged it as a bug. As soon as I learn more, I will share it here or on my Website: https://captivateteacher.com or my YouTube channel: https://YouTube.com/captivateteacher. Please let any other Captivate users who rely on Vimeo videos know about this issue. I hope that Adobe will correct this quickly. If you need to report anything to Adobe Technical Support, you can email them at CaptivateHelp@Adobe.com or fill out the form at https://www.adobe.com/products/wishform.html
