Sometimes a problem can occur where the end user's connection to the bank is lost or disconnected.
We recommend they try the following:
1: Login into app.aiia.eu with your connected email
2: When logged in, click on "Banks"
3: Click the bank connection you experience issues with
4: Click the blue "Options" button
5: Choose "Update account"
6: Log into the bank
If the login is successful, the end user should check whether the connection is reestablished with the service that they use.
