Synchronization with the bank account can be triggered manually up to 4 times per day. To do so, click the sync icon in the header bar.
Unfortunately, automatic synchronization is only available to a limited extent because the bank requests two-factor authorization (MFA) at irregular intervals.
If the update of bank transactions does not work or no new transactions are displayed, first check the synchronization status.
In the "Status" column, check whether the account is shown as "OK" (green dot).
