I think this expected especially since many are seeing the same thing. We from the start communicated that the noindexes would over time convert to 404s when the WPM pixel URLs changed for versioning. This will not affect your performance. The 404s will clear over time. What we don’t want to see is an increase in WPM noindex reports.
