GMail only available when notifications occur?

[Paul Hands]

I have GMail working on my Gear S2, and it's great - when a new Gmail arrives, I get the notification, I can rotate the bezel to access the new emails. However, once I've gone through the new stuff, I can't access GMail to look at older emails. Is this possible? There's no GMail app in the apps list, so I can't access GMail unless a new email notification has occurred....and sometimes the notifications don't seem to happen.
