App not working.

I have used this app for about a year now and over the last couple of weeks it has been acting up. First it told me it couldn’t verify my payment method but I got a receipt that showed .00. Today it gets stuck when I try to select a pump number. Frustrating especially since I don t carry my wallet to get gas anymore.

Bring back the prices!

Update 4/2: this app just keeps getting worse and worse!! Now it won’t apply my 15 cent discount for my Sinclair card, and the prices listed are never right! I went into the store and had the ABSOLUTE rudest employee ever who refused to help and said she has never been trained on the app and doesn’t know how to use it, because she doesn’t buy her gas here. That doesn’t even look good, Sinclair!!! Come on now!! You are better than this. The update is horrible!! fix it already

Really not happy with the latest update. I liked being able to quickly look at the map and see the prices for gas stations in my area - now I have to click on each one individually to find prices. Very tedious and annoying. Fix the map and I’ll fix this rating!

Great....when it works about 1% of the time

This app is the most frustrating app I’ve used. It is an excellent idea if only it would work. The few times that it did work I didn’t get the discount. The many times it did not work was “opps something when wrong” error. Standing next to the gas pump, “your too far from gas station”; goto another Sinclair , still thinks I’m at the other gas station. Prior to this it cleared all my information... name, credit card, etc. re-entered everything and then as soon as I entered the bank card I get a fraud notification from the bank and it says your account it locked. It is one problem after another with this app. Once again great idea I’d only it worked.
