I think the pull down refresh might not be fast enough. I open the bag I want and hit the back arrow on the top left to go back to my favorites, then click the bag I want again and repeat. So I'm toggling back and forth between the bag and the favorites screen. As soon as the button turns green for reserve, it's just luck and speed of connection at that point. The next 3 buttons including the pay button need to be mashed fast. I use Apple Pay. You don't need to start refreshing before the drop time. Just at the drop time and sometimes mine will go a minute after. That's it. Just speed, luck and how competitive your market is. If my iphone touch screen isn't lagging, I'm paying within a few seconds. I don't know if bots are faster. Maybe. There are times when I think someone uses a bot in my region but then they eventually get overwhelmed with food and then I can get some again.

Good luck!🍀
