H4 drop box status shows no status

Hi All,

Good day….

My wife had an drop box on 10 January 2022 in Hyderabad H4,
Today 12 Jan 22, When I cross check the status it shows “no status”…
Documents added:
1.My wife took previous and latest I-797 copies of mine…
2. marriage certificate
3. My old visa copy

May I know reason why status is not changing any one face similar…

Please advice.
