Wanted to put out 2 issues that we have seen and wanted them to come up in search if someone else is having the issues.
1. For Azure AD Authentication \ Windows Authentication. Per the config installation you should have your "Tenant ID" in the Domain Name (Tenant ID) field. This has since changed, it is now not your Azure AD Tenant Domain ID, it's your FQDN that you login with. For instance, remove the "onmicrosoft" portion more then likely.
2. The Process Servers weren't working, thus anything in your Process queue wouldn't have attempted to run. So any automated tasks or reports you would be having wouldn't be working either.
