Hey! You get it
I’m not particularly up on my American vines, but I ran it through an ID app and it suggested Fox Grape, Vitis Labrusca. Any signs of fruiting? I had no idea that various wine grape varieties were bred from this species, but might be a good find.
I ran it through a couple of times with two pictures and this is what it came up with both times. The app is not fool proof though so could be completely wrong. It also suggested bur cucumber and english ivy as secondary options. I know it’s not the ivy.
