Forms Error: This content cannot be displayed

[DanielaH]

Forms in IE 11 are no longer loading at all  - anyone having the same problem??

The error suggests a problem with the frame, perhaps the HTML frame used is no longer supported in IE 11.. however if this really relates to a HTML update including a feature that is not supported in IE then several others may have the same problem. Any ideas anyone?

The forms are still loading in Edge and Chrome. 

I am using IE version 11.850.15063.0

Found the problem:

When I go to https://web.powerapps.com it appears I was not authenticated. Going there authenticates me and subsequently the error no longer appears.
