So, first of all. Spectrum runs great using safari on iOS. But, when adding to the homescreen as a shortcut, iOS recognises that spectrum is a web app resulting in a fullscreen loading experience as if it was a proper application installed on the phone. This is great! But there is a bug where it will not share logged in information with safari and trying to login simply opens safari where I am already logged in. A way for the iOS web app when launched from the homescreen shortcut to share the login status and information with Safari is needed.
