While Cloudflare generally improves speed, a temporary slowdown can occur. This could be due to a temporary issue with Cloudflare's servers, congestion on your local network, or a problem with your internet service provider. Try flushing your DNS cache (Settings -> Apps -> Clear Cache) and restarting your device. If the problem persists, contact your ISP.
