I work for a global creative agency. We use Creative Cloud for all of our lockups, logos and vector artwork.

Since updating to InDesign 2021, we've noticed that all Creative Cloud links are broken and when we export a file with embedded InDesign documents within it, we need to go through and open every single InDesign file again.

We now have to check every single link in every single exported PDF as there is almost always some broken assets that show up as white boxes.

InDesign doesn't give any alerts for broken links in this instance either.
