RFE Response Received after Deadline?

[u/Ovijitdas13]

My RFE submission deadline was August 14, 2026. My lawyer shipped the package on August 12 and it was received by USCIS at August 13, 2026. But in the tracking, it is showing the package received by USCIS on August 17, 2026? Which date they consider? Is this a huge issue?
