MoneyWiz connects to banks via various data aggregation providers, such as Yodlee, Plaid and Salt Edge. We don't connect directly. Unfortunately it's beyond our control to add new banks, as it's entirely up to our data providers. For that reason, if your bank is not currently supported, we can't do anything about it. One thing you can consider is to contact the providers to ask about possible new integrations, however we cannot assist with this process.
An alternative is to connect the banks that are supported and manage the rest manually in MoneyWiz. You can import your transactions from bank statements or enter them manually, and you can periodically check if support for your bank has been added.
