We have recently encountered an issue where external partners, who have Box accounts and have successfully accessed and edited documents in the past, are now unable to open them and are getting frequent (~30 seconds) error messages that their session has expired. Does anyone know why this is happening or what I can do to troubleshoot/support the external people?
