Yesterday I logged into LinkedIn, and shortly afterward I got an email saying:

Your request to activate Remember me on your Firefox, Mac OS X in Boston, Massachusetts, United States was not successful. This is because you have 2-Factor Authentication enabled on your account for additional security.

This was followed by information plausibly matching my last login. However, I didn’t know what “Remember me” is, and I certainly didn’t intentionally activate any feature by that name yesterday. This sounded like a bug. I went into LinkedIn’s help, which makes it difficult to contact a human, and eventually figured out how to report it. If it was happening to me, I figured, it must be happening to others.
