Sorry to hear about your difficulties. Just to ensure I understand correctly, can you explain more about the duration feature you were using previously?
I'm a content creator so I use Adobe Express for making edits. The duration feature is available in Instagram reels and Youtube Shorts and for each scene there are several edit options which includes the duration of the scene and also there's a feature in duration that says apply to all the pages. They both are not working for quite a while. Therefore it takes me double the time making the same edits.
Thanks for your response. Could you please let us know the platform you are using? Did you get any error messages? Is it on a desktop or mobile? Can you please share a screen recording of the issue to investigate further?
