No Warnings about Missing Files? (2.9)

When I open a .blend file that includes Linked objects with broken file references, I get no report / warning (see screenshot). How do I enable these?


TL;DR. I’m taking a university course and my teacher who also have 2.9 (I believe) gets this report, whereas I don’t (I’m also using 2.9). Is there a preference setting for this that I’ve mistakenly switched?

TL;DR2. I know I can open an Info Editor and then go File > External Data > Report Missing Files, but that experience is buggy since I have to actually click inside the Info Editor to get the reports to show up in that editor.
