I am confused. It is titled as "New robocaller recordings". The newest ones under that section are from October 25, 2017. However, the "Most active robocallers (Past 24 hours)" has records from later than October 25, 2017.
I noticed that under "new robocall recordings" the recordings are all from October 25, 2017. Not sure if this is a bug or you stopped updating them on that date or something.
