SharePoint legacy app access control vs Conditional Access legacy authentication
If we have a conditional access policy that blocks legacy authentication, do we still need to set the SharePoint access control setting of 'Apps that don't use modern authentication' to block access? Is having a conditional access policy blocking legacy authentication for 'Exchange ActiveSync' and "other clients' not sufficient? Also, conditional access policy allows us to run in report-only mode or even test with few users first. Whereas there doesn't appear to be any such controls available for SharePoint setting.
