Did you get a receipt from USCIS for OPT/STEM OPT?
Specifically for the Lewisville lockbox.
UPS shows my application was delivered on 11/18/2020 but don't have a receipt yet. Neither has the check been cashed.
Are you experiencing similar delays as well?

I applied around the same time and got my receipt this week, Phoenix lockbox. Looks like USCIS is severely impacted by the pandemic -> https://thepienews.com/news/opt-lockbox-delays-students-consider-taking-legal-action/ Hang in there.
