Simplifi supports AOD Federal Credit Union, but not the Visa card that the credit union offers. Apparently, the credit card is serviced by PSCU, which is not supported in Simplifi. Because the Visa card transactions appear on a separate site from the credit union's savings and checking accounts, when Simplifi syncs with AOD, it only downloads my banking transactions and does not download any of my credit card transactions.
The website for the AOD Visa card is https://apstp.pscu.com/
I understand that PSCU services credit cards from several regional credit unions, so adding PSCU might incorporate many new accounts. I really hope this bank can be added with the next round of financial institutions.
