Having no problems in any other browser but user testing is revealing locking up/freezing on slides which contain video. Also some button functions are just not playing nice on Edge but work perfectly fine in Chrome. The general experience in Edge seems subpar compared to other browsers but like most corporate environments Edge is the first available offering when it comes to browsers.
Captivate doesn't work well with Microsoft Edge at ALL. I submitted many issues over a year ago to Adobe showing how some of my content would not work with Edge. They admitted it was an issue with no ETA.
Edge will soon be Chromium-powered and my hope is that this issue will be resolved.
In the meantime, we tell our clients that our training is only supported by Google Chrome browsers. Surprisingly to me, nobody has complained.
We have noticed that the content does still work in Internet Explorer.
