I just found out through Emma that USCIS denied tier 2 request to expedite my case, which does indeed show that, as
@Sm1smom and
@SusieQQQ pointed out, they are working even if the physical office is still closed.
And I guess it makes sense they denied the request since the case is already underway and it wouldn't be about that; but I think it could also be an indicator that they do not intend to approve it without an interview, which seemed more plausible than being interviewed on time as the agent also mentioned they currently do not have a date or timeline of when they will reopen.
19 days left, and hoping for a miracle honestly.
