Kara from Google said in the Google My Business Help thread that they have done a user interface refresh of the relatively new Product Editor interface. This can be found on some Google My Business consoles under the Product beta link.
Google began this beta a few months ago and I guess based on the feedback, Google did some user interface changes.
We’ve refreshed the User Interface of the Product Editor (Products (Beta) tab), and opened it up to more Retail merchants. Currently, items added through Product Editor appear exclusively in business profiles on the mobile version of Google Search. At the moment, they do not appear on or influence search results.
Kara made a point to explain that this products do not appear in search directly at the moment and also have no influence on search rankings.
You can learn more about this feature over here.
