Hey Dave, sorry about the late response. We shipped a fix for this a few minutes after it started occurring, apologies for that.

Regarding the global search, I see a UI improvement we need to make.
After typing your query, you will need to specifically select the "Ask AI" option (either clicking, or can use an arrow key to select then press enter)

I realize this is a confusing UI. I'll pass these notes to our designer and we'll get this improved promptly. Thanks for pointing this out.
