CRM API auth token creation does not work on iOS 8 browsers (browser mode)

CRM API auth token creation does not work on iOS 8 browsers (browser mode)

We use the Browser Mode CRM API to create auth tokens in our iOS app. The URL we hit is  https://accounts.zoho.com/apiauthtoken/create?SCOPE=ZohoCRM/crmapi . This returns the token inside a "pre" tag in the response. This used to show up fine in iOS 7. But, in the new iOS 8, this doesn't work anymore.

iOS8 Safari browser seems to treat the response as a file while Chrome in iOS8 just gets stuck with a "please wait..." screen. 

We are dependent on this API for our Zoho integration and hence this is a showstopper for our app. 

We launch the URL inside a UIWebView control, which is the equivalent of iOS Safari browser.

Please let me know if it is possible to talk/chat with a technical expert so that I can explain the issue in more detail. 

Thanks,
