Stream "sign in" or "sign up" page blocking video views

We are tyring to use the embed code for MSStream videos in a sharepoint (online) page, which as other users have said works fine in most browsers on the desktop except for Safari (which has cross domain protection enabled by default - turning this off allows it to work).

 

However we are trying to load the sharepoint page with an embedded MSStream video in a webview control using Xamarin forms however get the following error:

 

11-14 11:55:07.426 W/zygote  (18172): Attempt to remove non-JNI local reference, dumping thread[INFO:CONSOLE(0)] "Refused to display 'https://login.microsoftonline.com/common/oauth2/authorize?response_type=id_token&client_id=<blah blah blah>' in a frame because it set 'X-Frame-Options' to 'deny'.", source: https://<oursharepoint host>/Pages/Videos.aspx (0)

 

Same page works in Chrome, IE, Firefox on the desktop, ie user is signed in to SharePoint (online) and MSStream embedded video loads.

 

Safari does not work, and gives the following error in the console (similar to the Android emulator):

[Error] Refused to display 'https://login.microsoftonline.com/common/oauth2/authorize?response_type=id_token&client_id=89bee1f7-5e6e-4d8a-9f3d-ecd601259da7&redirect_uri=https%3A%2F%2Fwebshell.suite.office.com%2Fiframe%2FTokenFactoryIframe&state=0e6d9d94-16b5-4793-96e4-670306e2801f&client-request-id=c942ede5-0c60-4c79-906b-193ece6ecddd&x-client-SKU=Js&x-client-Ver=1.0.15&nonce=b6e7a5d3-9a75-451e-aef1-77dd6a56d065blah blah blah>' in a frame because it set 'X-Frame-Options' to 'DENY'.

 

Chrome on the mobile device loads the page ok.

 

Can the X-Frame-Options for login.microsoftonline.com be opened up a little to allow working in an IFrame or at least from other Office 365 services (ie SharePoint)? And sooner the better!!! Otherwise we'll be looking for other video solution options...
