How long does it typically take USCIS to acknowledge receipt of RFE response?

[odobo]

Hi all,

In your experience, how long does it typically take USCIS to acknowledge receipt of RFE response?
i.e., how long from the date of package-receipt (from mail-carrier such as Fedex) to USCIS actually changing the case-status online to '"RFE response received" ?

Thanks.

I think there is no clear answer for that...

I got an RFE as a surprise on the mail and respond to it , I didn't even get the RFE sent or RFe received status on the uscis site

some pople I know got the RFE sent status but never the RFE received

During these Covid times the updates have not been very reliable
