Upcoming Exchange Online Device Access and Conditional Access changes with Outlook mobile

Ross Smith IV  and The_Exchange_Team  I'm looking into our CA policies to check which would start processing the device access rules and pose an issue (have the org setting on quarantine) Initially you mention that the CA policy does not even have to be targeted to mobile devices. 

Is it than correct from august onward

If your User is targeted in any CA policy which does not have Grant access controls selected will process the Device access rules ?  

Device access rules are also applied if the one of the CA policy is set to Block or use Session controls ?

Is the webbased access to exchange online  also blocked if a device is quarantined or only the outlook app on IOS and Android ?
