Possible bug: payment method mixup

Hello. I am a customer of Familiars in Northampton, MA USA. Familiars is a cafe that takes its orders though a square.site. I am reporting this possible bug here, because it probably doesn't look like a bug to the Familiars people, and because I couldn't find another way to reach a human at Square.

Here's what happened. After picking my order and going to checkout, I selected Cash App as the payment method. At that time, it successfully spawned the Cash app, linked my account, and returned to the shop's checkout form. Then when I tried to submit the order, form validation failed; it wanted my contact info.

So far so good. But because I did not feel like entering my contact info, I then tapped on the Google Pay option. I had used that many times before, and remembered I didn't have to enter my contact info.

The order seemed to finish successfully at that point, after the usual few seconds' wait for background activity. Except I soon discovered that the payment was charged to my Cash account & its linked debit card!

So, there are possibly two problems here. The minor one: that I am possibly getting away with not passing in my contact info when the app or vendor or whatever might need it. The major one: the wrong payment method is charged.

I do not see a pending transaction on the card linked to my Google Pay, nor any other sign that I was double-charged.

This happened with Firefox for Android.
