ERA5-Land hourly data from 1950 to present missing data


I have downloaded the ERA5-Land hourly dataset from  01 Jan 2011 to 31 Dec 2021 (2m temperature) (Fig.1). The entire month of december  2021 is missing. The total number of values is 95689 and it should be 96432.

This values are not available yet? Where can I clarify this type of question?

Thank you,
