ADFS and MFA in Microsoft Browsers

Question

Hi

I'm after some help or suggestions as to what could be causing some odd behaviour in ADFS. A little background first. We have 2 WAP severs sitting in front of 2 ADFS servers which cal on 2 third party MFA severs, in our case Securenvoy.

I'm using a per relying party trust for testing purposes and getting for following behaviour. When I hit the URL using Chrome I can authenticate and get the token prompt successfully after the initial username and password prompmt as expected. However if I use IE (and version) or Edge, instead of the token prompt I immediately get an error page after the initial username and password:

For security reasons, we require additional information to verify your account
An error occurred
An error occurred. Contact your administrator for more information.

Has anyone come across anything similar before? I am assuming there is some option or setting in either WAP or ADFS that isn't set correctly but I just can't see anything obvious.
