When this new 3.x.x version of the app was released it was a Charlie Foxtrot of epic proportions. I stuck with the old one for a long time. Then after about 20 updates I installed it. The main reason I installed the new one is because I got a new phone and all of my old apps got automatically installed, and I missed it when the MyPilot app got installed. Fortunately, with 3.3.x it's not to bad.
I use it. I've input the FleetOne card for payment and all the other information needed. I've been at a PFJ and it's found the correct location, and it's given me a pump start code that has worked every time, and the receipt is then shown in the phone. I would give it a thumbs up. For Android.
