I recently worked with a client planning to deploy Azure AD Cloud App Discovery.  When accessing Cloud App Discovery through Portal.Azure.com they received the error message:

Could not create Azure AD Cloud App Discovery.
Something went wrong while creating Azure AD Cloud App Discovery.

I wanted to make this post to inform users that this version has been retired, this is noted in Microsoft’s documentation.

Cloud App Discovery is now retired and was replaced by Cloud Discovery in the Cloud App Security framework.
