There is currently a problem with the process for granting access to some Springer content with a 2022 publication date. The issue is affecting books and journals. We are working to resolve the issue as quickly as possible.
As a result, you may find that the 'Download PDF' button is not appearing for eBooks with 2022 copyright year. If you need access to this content immediately, we can manually activate it. Please contact firstname.lastname@example.org with your request.
We apologize for any inconvenience caused.
