Don't get pairing option for Youtube

I usually use my Webcaster X2 on Facebook, and have just completed a stream on there, but I now wish to create a stream on Youtube - but I am not being offered a way to go to the pairing screen. I have both platforms ticked on the preferences page.
The only way I have found to get to Youtube or to switch between the 2 platforms is to hit factory reset, which then offers me the platform choice.
Is this right, or am I missing something?

If you have both options for Facebook and YouTube enabled in Preferences then when you click the button in the top right corner you will be able to exit back to a destination selection screen. Here you will be able to click on YouTube. Alternatively you can double press the multifunction button on the Webcaster X2 to switch platforms.
