SoFi credit cards are not supported at this time. It does look like the account type is in beta right now though so it seems our data provider, Yodlee, is working on it. We’re not sure when it’ll be working, and we don’t escalate service requests to them for beta account types or institutions.
My recommendation would be to go through the re-add steps for SoFi periodically without deleting the connection first and see if the credit card pulls in or if it’s pulled in but no data is flowing, just keep an eye on it and eventually it will probably start working.
