"Compare files" and other tools grayed out in Adobe Acrobat Pro on Mac

[Eccentric_Sunflower4743]

I am running Adobe Acrobat Pro version 2025.001.20432 on Mac. I primarily use this account for the Compare files functionality which has worked great historically. Today, however, when I opened All tools I noticed the "Compare files" is grayed out along with several others (Add rich media, Redact a PDF, Apply PDF standards, Use print production, Use guided action, and Add search index are also grayed out). All other tools are accessible as usual. I have verified that I am logged into my Adobe account and have no files open in the software.

Any idea why these tools are suddenly inaccessible?
