Have you also received a notification in search console about new page indexing issues detected on your site?
According to John Mueller, there is no change in the processing of your site and that it is purely in the reporting in the page indexing report. More fine-grained page indexing issue information is now available in the report and as a result, some may see a rise in the portion of issues being reported.
According to Mueller, there just has been a delay in the annotation of the report but it has been updated now.
