Disparity in Office 365 home experience

My view  is also the second screen shot with the search box.

The issues with not having the search box are a little strange.

On the first release/communicatiosn site side of things...one thing to note, if your tenants are set to first release, you can probably lay off the refresh button for now as they haven't quite rolled our to tenants in first release.  It's only for tenants that are set to first release for select users.  I beleive the rollout to tenants set to first release is set to start next week.  See this tweet from Dan Holme on July 5 - https://twitter.com/danholme/status/882693340629680128
