For posterity a short summary of two issues we recently noticed and reported in github:
Changing order in author list by/for Corresponding Author ignores authorization from OJS user profile · Issue #333 · pkp/orcidProfile · GitHub : apparently changing the order in the author list affects authorization from the OJS profile for Corresponding Authors
Problem(s) with authorization after submission is published (e.g. when using QuickSubmit tool) · Issue #334 · pkp/orcidProfile · GitHub : when using the QuickSubmit tool authors will authorize their ORCID record AFTER publication of a submission - in this case updating their ORCID record might now work.
