[PetalAve]

Need some help. I'm using Dawn Theme version 12.0.0

I added an app to help with date picking for orders and store pickup but now my cart isn't scrolling so i can't click check out button. i can only see it if i zoom out the whole page.

Have tried it on firefox and safari both did not scroll
