Hi Colin,
Can you provide me some examples which EasyBlog posts in particular you are referring to?
To allow EasyBlog posts to show in ES group stream, you have to make sure:
1.
EasyBlog group blog app is installed in EasySocial applications. I noticed your EasySocial does not have this app.
2. The post author is the respective ES groups(
