title: Do cookies work on iPhone when an iframe is embedded in another site?
body: <p>I am using cookies to check whether a user is logged in (with Devise).  When the app is embedded in an iframe (on <a href="http://lifeelevated.life/players/" rel="nofollow noreferrer">http://lifeelevated.life/players/</a> ), and I access the page from my iPhone 6s, the browser doesn't list any cookies and the server isn't able to determine who is logged in.</p>
