Skype on the iPhone won't let me use video on group chats?

I just downloaded the app so it shouldn t need to update. How can I get video.

Currently supported clients are:

Skype for Windows Desktop 6.11 and above
Skype for modern Windows 8.1 version 2.4 and above*
Skype for Mac 6.11 and above
Skype for iOS 4.15 and above
Skype for Windows Phone 8 version 2.13 and above
Skype for Android 4.5 and above
Skype for Xbox 1.2 and above
Skype for Kindle Fire OS
Skype for Blackberry 10

Video calls can only be made between two people. To do multi-person video calls, you must upgrade to Skype Premeium.
