| **Error Message**             | The end user has a language preference other than English. This could potentially cause issues with the integration for this specific institution. Have the end user change their language preferences to English for their accounts in order to get the best experience.​                                                                                                                                                                                                                                                                     |
| **Common Causes**             | This could be a prompt from the financial institution for the user to take a specific action during add account process. These prompts may include actions such as : * Updating customer's contact information before they attempt to add accounts * Accepting e-statements or new terms and conditions * Directing the user to login at the bank website etc. ​Until the end user resolves the issue, data access for certain capabilities can be limited (e.g. account owner details may not be supported) or data refresh can be impacted.​ |
| **Troubleshooting Steps**     | Data Connect alerts will automatically prompt the end user when they are in session on your behalf to take suggested remediation action associated for this error. ​ Best Practice: Developers may prompt the end users to log into the financial institution and take timely recommended action so that data access/refresh can be resumed.                                                                                                                                                                                                   |
