Entra SAML SSO is timing out on Mobile Edge browser:

Question

We are having the following issue:

#1: We are using Entra ID accounts with required MFA with Intune. When we attempt to sign into the O365 portal in Mobile Edge on iPhones and Android's we are able to authenticate, but after authentication we get the message that the request must be completed in the EDGE browser. (Even though we are already int he Edge Mobile browser) When we click on the "COMPLETE REQUEST IN EDGE BROWSER" the request times out.

#2: We have installed Company Portal on the smartphones, and made Edge the default browser, but we are still having this issue.
