F5 Big-IP Edge Client (uses internet explorer by default?, not compatible with Duo Yubikey Authn)

Hi nicholse - I think your post got caught in the holiday traffic slump... I've asked one of my teammates to come take a look. 

A little research suggests that there may be a version of the F5 Big-IP Edge Client that supports Chrome or Edge via Duo's Universal vs. Traditional prompt. See url below. Can anyone verify this? Or do we need to modify the policy somehow to use Universal vs Traditional? As it is, our only choice for getting connected to VPN securely is via the Duo app because we don't allow phone call or sms. Chris_Zhang ?

The release notes from 7.2.1 suggest that it shold work?

Looks like I am using 7.2.2 yet it doesnt work...

I also tried modifying the IE compatibility keys for rundll32.exe and  f5fpclientW.exe using 2af8 and 2af9 without any luck as referenced here and here:

I got this reply from Duo today. Can anyone coroborate? Is this the only way for us to get the Yubikeys working with F5 Edge Client?

From Duo Support:
"In terms of what F5 Edge Client versions support using those browsers, I am not sure. I will say, if you want to utilize this Universal Prompt with F5 as you mentioned, the best way to do this is F5 BIG-IP APM with OIDC Web Duo Prompt. Note: this does require Big-IP firmware version 13.1 or later."
