Can't buy anything on the app because the coupon locks it up.

I have a coupon to make a purchase by downloading the app. (on another account)

I am able to get the coupon code with no trouble. The problem is that when I view a listing, the app freezes and I am unable to scroll down to read the listing, watch or unwatch, click the X to close the coupon reminder, and even rage shake doesn't work.

The only thing I can do is swipe up to close the app.

app version 6.242.1.3 on an newer iphone

Here are 2 examples where you can see the coupon. Nothing is functional on the screen.

(no I'm not trying to buy my own items from another account, I just used them as examples rather than someone else's items)
