AR-11 Submitted online Nov 17

I submitted an AR-11 online and my spouse (sponsor) submitted an I-865 two days later by priority mail. I was supposed to receive a response on December 1 but didn’t. My address on my profile also hasn’t changed.

We have a mail forwarding set up and I usually receive all communications online anyway. Do I need to do anything else at this point or is it likely just delays?
