I couldn't stand it anymore so I called and after three attempts, I finally got through to an agent. He was very polite and kind - that was a plus. He actually checked the system (or at least put me on hold and pretended that he did. LOL) after he took my receipt number. This was after he gave me the spiel about application packages can sit in the mailroom for up to three months. He came back and told me that my receipt number has not yet been associated with a package so that means it is still in the mailroom and they are officially working on packages received on January 20, 2020. He didn't offer any explanation as to why people whose packages were received after mine (after February 10) have already receive AOR1. He did mention that if the package was marked urgent, they would process it faster (I guess some people do that for resubmissions???) However, my nerves are calmed as I feared that they might have returned my package. Anyone else in this situation I hope this helps.
