Picture-in-Picture Now Broadly Rolling Out to Non-YouTube Premium Subscribers
YouTube is now broadly rolling out the ability for all users, regardless if you are a YouTube Premium subscriber or not, to utilize the app’s support of Android Oreo’s Picture-in-Picture feature. By all indications, this is a cloud-side change so as long as you are running the latest version of YouTube on your phone (v 13.24.59 for those keeping score at home), you should see the update now or very shortly.
Up to this point, PiP has been limited to YouTube Red previously and now YouTube Premium as a benefit of the paid service. With this change, assuming that the content creator has given permission for PiP to happen, all YouTube users should be able to utilize the feature.
