Resolved - We have deprecated - https://www.crossref.org/deprecated/ - our previous Metadata Manager tool. Members who previously made use of Metadata Manager to register their metadata should move to our new form - https://manage.crossref.org/records. Please contact our support team - [email protected] - if you have questions. - IF
Jan 2, 19:06 UTC
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 - [email protected] - if you have questions. - IF
