The app doesn't work at many gas stations. So far terrible experience. Update: 03/07/2022 Mobil sources tell me the company is denying there is an issue and telling hundreds of thousands of customers that have been complaining to them via the 800 number and online that it is their banking card. the fact is the issue is a software issue with all the computers at the pumps. Mobil is aware of this but doing nothing to fix the issue and causing motorists plenty of problems including patience and the convenience aspect. What i would suggest is everyone switch to BP. BP also has points program so no hard loss for anyone.
