Teaghan is doing great. She's almost there

. However looking at your video I think maybe
she doesn't know where "there" is yet.
Perhaps I'm totally barking up the wrong tree but I'm wondering if it is to do with you currently clicking her foot returning to the floor, so she thinks, "Paw on button, paw on floor = treat." I can see that you are clicking the sound of the Easy Button but Teaghan is used to the click marking her behaviour not the behaviour of the objects she interacts with.
I think the fact that when you withhold the treat for a moment and she just stands and stares at you rather than whacking the button again and saying "Look!!! I hit the button where's my treat!" indicates that she is seeing the foot on the floor as being what is earning the reward, so she is looking at you saying, "Look! My foot is on the floor, gimme my treat!" Also the fact she's not hitting the centre of the button suggests she is skimping.
If I was you I would click the instant her foot makes contact with the button every time, giving single/ordinary treats for silent paw contact but jackpot (or buffalo brownie

) the ones where the Easy Button speaks. That way you are giving her a bigger reward for whatever was different about
her behaviour when she hits the Easy Button hard enough.
Hope this helps
