Weird one! I tried to search for the phrase “disabling voice replies siri” and all that is returned is a nearly blank page that says “No Events For The Selected Date.” There is a quick flash of search results, but in a fraction of a second it’s replaced by the message.
Using Kagi search on Orion iOS, 1.4.20. It happens from both the url bar and when typing it into kagi.com.
In Safari I get the same strange response, but at least it’s followed by the search results.
It does this every time I try it.

I expected search results!
