** UPDATE**
I have managed to sort it finally by thinking outside the box
😅 Such a odd way to set it up.
So click on the left wallet app (circled) >then go back onto that same page it then allows you to select google pay wallet. Select google wallet this time, get out of settings and bosh it should work if you double press!
Such a strange way of setting it up.
You learn something new everyday I guess!
