"User authentication failed. Your account should be relinked"

This error message is appearing when an interviewer, who is on teh server with assignments is trying to synchronize completed interviews. How do we get around this?

Please post a screenshot of the message.

Re-linking is explained here:

This must be either an error in translation to Vietnamese in Survey Solutions or an error in your translation of that message back to English.

The correct translation in English is:
User authentication error
Your account was relinked to another tablet

The message doesn’t require the user to perform re-linking, but rather notifies the user that it had already happened.

Thanks for letting me know. It was translated by a person in the field.
