What happened:
New Kagi ultimate subscriber. Searched "good Commodore 64 programming books". Top two results (only ones in top section) were reddit and hacker news. I want to block results from these sites. Clicked the ... under each to "block". Still showing a reddit result at top. Went into "settings -> personalized results" to make sure both reddit.com and news.ycombinator.com are listed as blocked. Tried searching again. Still seeing reddit.
Logged out and back in. This seemed to have fixed the issue with this search.
Opened a different browser and logged into Kagi. Tried "top Amiga programming books". Still seeing a result from Hacker News. Now showing a circle/slash icon.
As soon as a site is blocked the page should refresh and not show any results for those URLs. This should carry over into all future searches on all browsers/platforms.
