Open YouTube’s settings menu, either on your phone or on the website, to activate pinch to zoom. As long as you have a YouTube Premium subscription, there should be a “test new features” option. The zoom capability is currently the sole functionality available for testing. It seems that there is a lag between choosing the test and being able to perform the pinch gesture since we were unable to zoom in closer on any films right away after turning it on. However, once activated, you should be able to zoom in up to 8x.
