Google changed the frequency of data updates for the applications in the "Index Status" report in the Search Console. This information was stated by Data Anomalies service.
From now on the data will be updated every 3-4 days instead of doing this every day. Google does say that the changes are designed to improve system performance.
It should be reminded that now Google holds the Update Search Console infrastructure, which may become a matter of delays registrering data in some reports.
