Sudden drop in visit‑data file size

Hi,

I noticed a sharp drop in the daily visit file size on 23 Feb 2025.

During the previous week, daily total size was about 10–14 GB, but from 23 Feb through 12 Apr 2025 they have been only 3–5 GB.

Was there any change to the sampling, filters, file format, or device coverage around 23 Feb 2025?

Thank you!
