It looks like your metadata update deposits were not successful. You should have gotten a submission log email (sent to the email address that’s in the <email_address> tags of your submitted xml file) with the following error message:
Record not processed because submitted version: 1618996637 is less or equal to previously submitted version 20210405085454211
That’s happening because you didn’t update the value in the files before resubmit them.
Every time you update the metadata for an existing DOI, that timestamp value needs to be numerically larger. So, if the first deposit had 20210405085454211 the update deposit has to have a number that’s at least 20210405085454212 or higher.
All that said, if you only need to update the resolution URLs for these DOIs, and not any of the other metadata, you can always prepare a spreadsheet with the DOIs in column A and the new resolution URLs in column B and send that to firstname.lastname@example.org. We can use that file to update the URLs for you.
