I received confirmation from the support team that the cause of the issue has been identified and a once-off fix has been applied, relevant to my instance. Further work will probably be needed to support others who will inevitably encounter similar meta-data issues in future.
Here is the feedback from the support team on my instance:
"This is indeed related to metadata on our end storing the old e-mail address and when linking it was using the old email address. We've gone ahead and removed the old email address internally. Please proceed to re-add your new email/account for paypal. Reach back if the issue continues."
