Thanks for your response.
We checked about this with the relevant department and it seems that this feature hasn't yet been released for all iOS devices. As such features become available on different devices with time, it's possible it isn't yet rolled out for the device you use. However, we're working on making it available on all devices at a later stage.
Tip: Make sure you don't miss a thing by enabling automatic updates on your device.
Hope this helps. Let us know if you have any more questions.
