Investigating - Several members have reported that their sessions have been dropped (screen turning white) when attempting to add contributor metadata to their registrations within Metadata Manager - https://www.crossref.org/metadatamanager/. Members facing this issue should register their metadata without contributors and then use the new record registration form - https://manage.crossref.org/records - to import those records so their contributors can be added to the metadata. Please contact our support team - support@crossref.org - if you have questions. - IF
