Why is adobe express greyed out in indesign?

Hi ​@efficient_makere5c3,

I'm sorry to hear that the Adobe Express option is suddenly greyed out in InDesign, especially since it was working previously.

Thank you for confirming that you've already tested the same image and tried creating a new document.

According to this helpx  documentation, Edit with Adobe Express supports PNG, JPEG, PSD, and AI images in RGB color mode, but not CMYK.

Could you please try the following?

1. Create a new InDesign document and use File > Place (Ctrl + D) to import a standard RGB JPEG or PNG image directly from your computer, rather than copying and pasting it. Select the image and check whether Edit with Adobe Express becomes available.

2. If it remains greyed out, please confirm the image's file format and color mode, along with the language of your installed InDesign application, as the feature has certain format and locale restrictions.

3. Please also try signing out of Creative Cloud Desktop, restarting your computer, and signing back in to check whether that restores the functionality.

If the issue persists, could you please share your Windows version and a short screen recording showing the workflow from placing an RGB image to the Adobe Express option appearing greyed out?

Looking forward to your update!

Is it possible that this object is not intended for Adobe Express editing? Or is it the same image (or type of image) you were able to edit previously?
