The app was amazing on everyone Samsung I have owned (s7-8 and Note 5 - 10), but now I own the ZFlip 3 and MST support was stripped for my region. I was beyond upset about this. I use to use my phones to pay literally anywhere, but now I can only use my device at stores with NFC readers... I've enjoyed the luxury of not having to ask " Do you have tap and pay?" For years and it is truly disappointing that i can no longer use my phone at my preferred grocery stores (Kroger) 🙃
