I still don't know how to "go back" after viewing a video on the mobile app. It's so confusing. I just keep swiping stuff and eventually it works.

The google maps app has similar bizareness.

I guess somehow this all makes G more money, but it sure is painful as a consumer.

I'd pay money for a good hand-crafted (non a/b tested) experience. Competition should be the true a/b test :).
