Subject: [PATCH] Do not use WebKit for CookieManager operations in SSO (#2515)

* Do not use WebKit for CookieManager operations in SSO

This allows the SSO login to function again with devices that are not running IOS-11.

* Use WebKit for CookieManager operations only with iOS 11 or later

Detect OS version and use WebKit only when iOS 11 or later is detected.
This allows the SSO login to function again with older devices.
