A user's wellness data may not update even though there is an active connection in Human API. In rare cases, this is due to an expired access token for the source API. Please advise the user to go into your instance of Connect, disconnect the data source, then reconnect the same source. That will refresh the access token associated with the source and allow data to be retrieved. Depending on the amount of historical data, the process could take minutes to hours.
Please contact HumanAPI support if the problem persists.
