You'll soon be able to watch YouTube videos in WhatsApp7
Some of these new features have already been implemented into the app, but they are hidden to the public for the time being. One of the most recent WhatsApp for iOS updates introduced one feature that would certainly be very useful to users: the option to watch YouTube videos directly in WhatsApp.
Although it's still under development, the new feature allows those who can access it to watch YouTube videos in WhatsApp in the same manner as Picture in Picture mode. You can either drag the Picture in Picture mode to expand it on the entire screen, or you can open the YouTube video in a completely different WhatsApp window.
You can even drag the video window to the left or right of the screen without effectively stopping it so that you can continue to read your conversation. Apparently, the option to watch YouTube videos in WhatsApp fully supports iPhone 6 and newer devices, but Apple smartphones with smaller screens might be compatible as well.
