Session Policy - Conditional Access and Cloud App Security

Hello Everyone,

I noticed that CAS proxy is GA and some of the Office 365 apps are as well, such as Exchange, SharePoint, etc. However, I see Teams and Yammer are still in preview. Can I have a estimated date for when these two apps will become GA? 

Are there any implications other than URI context loss from those apps in preview?

Please share thoughts. Thank you. Maria Y.
