Pretty miserable app. For me, the main function of this app is paying and starting the pump without using my cards. That function works MAYBE 10% of the time. It lets you select a pump, and start the process, but then immediately cancels the exchange. Or. It just doesn't work at all, and won't let you even start the process. I've tried for years, through multiple different phones. Current a Pixel 3. Pretty disappointing.
