digi.me have partnered with Plaid to bring US financial records into the digi.me app. Plaid is a secure way to connect to your bank and other payment accounts, then import the data into your digi.me. You can access the new financial connector by tapping either "US Banks" or "Canadian Banks" in the add sources menu.
We're aware of an issue affecting our new finance connector which may result in an error when removing the source from your library. We're looking to address this as soon as we can. In the meantime, please wait for your digi.me to finish syncing new data, then try again. If this doesn't resolve the issue, you can open a new ticket with our Support Team.
