Facebook app warns to “Turn up your device volume to unmute the video“ when tapping on mute button.

When viewing a facebook video post. The video is muted. To unmute it, I tap the mute symbol. The facebook app pops a message up that says “Turn up your device volume to unmute the video“. I use the side volume controls to turn up the volume. It instead, will only change the ringer volume. I then go to the control panel to turn up the volume. The Facebook app doesn’t unmute the video, however.
