If you modify or update a linked file that's connected to several projects in Illustrator, Photoshop, InDesign, etc, they always update automatically upon opening a project that features that asset, or at least ask you if you want to apply the modification. This should also be a feature in Adobe Express!

If I have teams in the social media department working on templates that I've created, I want them to be using the latest version of our logos, or other assets.

If I have a logo saved in my Adobe Library, and I click "replace logo" or open it in Illustrator, make changes, and save over it, it should automatically update all projects featuring the logo.

I believe this is a feature in Figma, it should most definitely apply in Adobe Express!
