Setting up SSO for GoToMeeting with Azure AD

[dejavuguides]

I am testing SSO for GoToMeeting with Azure AD and I am getting this message when attempting to sign in to GoToMeeting. Can I please check if anyone has any ideas how to fix this?

I am using SAML 2.0, and I believe I have configured everything per the instructions but not too sure if there is something else in the LogMeIn Admin Center that I need to still configure given the message says I need to configure SAML still in LogMeIn. The SSO settings in LogMeIn I have uploaded the metafile xml and I checked the Login URL, Azure AD Identifier, Logout URL (Optional) and it looks fine. 

I am following these instructions:

The issue looks similar to this  but I am getting not getting any "company ID" errors.  https://community.logmein.com/t5/GoToMeeting-Discussions/SSO-for-GoToMeeting-using-Azure-AD/m-p/2023...
