Adobe Express is a full on disaster in Microsoft Edge... Crashes, freezes, display glitches all over the place - it's just awful. Great concept - hope you can work it out..
We're sorry for your experience with the new Express version. Could you please let us know when exactly does the app crashes? Are you getting any error messages? Have you tried using the other suggested browsers (Safari, Microsoft Edge, and Google Chrome) to see if it makes a difference?
