How can I verify if Cloudflare Warp is actually connected and providing a secure connection on my iPhone?

Once Cloudflare Warp connects, you should see a Cloudflare icon in your iPhone's status bar (at the top of the screen). You can also check the Cloudflare app itself; it should display a connection status and information about the server you're connected to. To verify a secure connection, look for a 'Secure' or 'HTTPS' indicator when browsing websites.
