I recently enabled the learning path on Dynamics 365 and instantly started receiving issues logging in, in fact anything I tried in Dynamics 365 would result in a constant flow of new tabs opening and then trying to close.
The page itself tried to you redirect to: https://www.crmdynint.com/Auth/v2//authRedirect.html#id_token…
Which if you browse to in another browser it shows as “Traffic manager monitor page”
The only fix for this was to use another browser to login to Dynamics 365 and then selecting “Opt Out of Learning Path”. I could then open up IE and use Dynamics 365 again.
So there is some sort of bug here with Dynamics 365 which is causing this it would appear.
