Before the "update", one could go to the item details page of a hosted feature layer, and either click on the View or copy the URL that takes you to the rest services for that item.
Now, if you click the view, rather than taking you to sampleserver#..., it takes you to your organization page with the item id, but can't navigate anywhere else.

If you copy the url and paste in a browser, it will at least take you to the REST server, BUT, will not pass any token data anymore, and will only show feature layers that are shared to the entire public.
How do I get to the REST service endpoints for services that are not share publicly, but rather to owner and/or organization?
Thanks,
