Q: I'm unable to set my PureWeb streaming experience to full screen on iPhone or iPod.

A: This is a limitation of iOS. Full screen will work on an iPad, but will not work on an iPhone or iPod.

// Fullscreen API presently supported on iPad, but not iPhone or iPod
This limitation is mentioned in App.tsx of our web client template

For more information about the various capabilities (such as fullscreen) and where it is supported you can check out online resources such as https://caniuse.com
