iPad Air 2 muting instagram because it doesn't have a mute switch!

Tried it, it's unmute in the Control Center but still the videos are mute

Yes I deleted instagram & Re-installed it, Restarted my device, Muted unmuted using Control center, Looked in the setting for further sound control, nothing worked

Still the videos start mute

In the iPad Air 1 this "automatic/default video mute" happens if the mute switch is turned on, but when I turn it off it's back to normal,

so now in iPad Air 2 it's acting as if the mute switch is on and there's no switch to turn it off (although videos in e.g youtube aren't mute)

Ok so basically, in iPad Air 1

Mute button switched off - videos in instagram play once you enter a video, sounds on

Mute button switched on - videos in instagram play once you enter a video, sounds off (but there's an instagram feature offering a "screen touch button" on the top of the video that you can touch and make the sound on) - regardless of the mute button being switched on

in iPad Air 2

NO mute button, and it takes the mute switched off status - I have to touch the "screen touch button" on top of the video to unmute, meaning Ill be missing the first part of the video, which already started playing without sound waiting for me to unmute it using the "screen touch button")

And theres no mute button to switch off and get out of the "mute mode"

Good idea, but what would instagram do if every device known plays videos with sound perfectly except iPad Air 2?
