For at least the past year (though probably longer at this point) I keep on being randomly kicked out to the "please sign in" page when I try to search from the kagi search results page (e.g. change a query after searching). When I make the change and press enter, I get kicked to the login page. When I go back to the previous page, and try the changed query again it usually works and gives me the results. Logging in on the login page I get does not help, and I still get the issue with approximately the same frequency. I have not found any correlation between my actions and the issue occurring, it really does seem to be effectively random. I have plenty of credit on my account.
I use firefox with a series of blocker extensions, which may be causing part of this issue, though it's strange that it occurs at random without any discernable pattern.
Search results are shown instead of the login page.
