Terrible app. Its given me error messages when making transactions then it'll charge me multiple times for the same transaction. I tried putting 100 dollars in and it processed my payment 3 times, even though the app only showed me 1 transaction complete message. When I called customer service, they told me there was nothing they can do and to try to reinstall the app. Garbage. I heard bad things about Coinbase before, but now I experienced it first hand. Download literally any other app.
