Update your applications to use Microsoft Authentication Library and Microsoft Graph API

Ok, need some clarification here. If we use apps that hit AAD Graph /ADAL and we don't update, what happens on 7/1/2022 ?

Apps using Azure AD Graph after this time will no longer receive responses from the Azure AD Graph endpoint. 

This statement sounds like all calls will fail 7/1/2022 or do you mean *only* apps that go directly to the Graph endpoint and don't use ADAL or MS Powershell modules that use ADAL ?

Apps using ADAL on existing OS versions will continue to work after this time but will not get any technical support or security updates.

Does this mean that if you're using ADAL.NET or MS powershell modules that use ADAL, that you will be ok, but no updates will be made for any issues , security or otherwise ?
