Lil Boat Boutique review for Point of Sale

I really love the POS app. I use it on my iPhone during my pop-up events. Since upgrade to iPhone 12, though, my tap and chip no longer will connect. I've seen this is a common issue on various message boards, etc, with still no resolution. Luckily I still had my chip + swipe that I can use, but it's frustrating not being able to take digital payments like google and Apple anymore.
