This is a test environment and I have two web application. One of the web application, my.contoso.com, has a site collection with My Site Host. The other web application, portal.contoso.com, has a team site.
But if I create a team site in my.contoso.com, which have the my site host, the Newsfeed Web part works perfectly.
Is it possible to have Newsfeed work properly while having Team Site and My Site Host on separate web application? Or it needs to be in same web application and different Site Collections?
