On Connected Accounts, click the trash icon on the institution card and confirm Are you sure you want to remove?. Sprwt revokes the connection at Plaid and deactivates all accounts from that institution, so they disappear from the page and from the dashboard and stop syncing. Transactions already imported stay in your ledger. You can connect the same institution again later; because the old accounts are inactive, Sprwt reuses them instead of reporting a duplicate.
