Not only will Simplifi not connect to Walmart OnePay, but neither OnePay, nor Synchrony will allow CSV downloads of their transactions. After converting PDF statements into CSVs, Simplifi NOW won't upload transactions via CSV. The human chat assistant incompetently bumbled around for an hour, sending me 2 CSV files of XML code only to tell me that the upload process is backlogged. What a joke. Simplifi - get your stuff together.
