Sometimes, usually once every few days, submitting a search into Safari takes me to the Kagi sign in page, where I have to sign in in order to re-type and submit my search. I can't find a consistent way to reproduce it. I'm on the iOS 26 beta, and it's been happening for a few weeks, so I assume it's related to that. But maybe not?
Expected: Submitting a query in Safari populates in the search in Kagi.com
Result: Submitting a query in Safari redirects to the Kagi sign in page.
