Called this past week, the woman I spoke to seemed low-key annoyed (but not rude) and said they don't do status updates over the phone, I said "ok, just checking because it's been 9 weeks and I wanted to make sure nothing was wrong" "No, nothing's wrong, you'll get an email. We're behind" was generally how it went. So I don't know if it's worth calling them if it's going to annoy them :/
No complete email yet. I don't think they understand that we're not asking for status update, we're literally just wanting to confirm our materials were received, because it would really suck for them to finally get to our app and say "oh no, for some reason we don't have this letter" or something, and then we'd have to scramble, now being 9 weeks behind where we thought we were. I know the chances of that are small, but like everyone's said, most other schools do this automatically. I know Einstein is not technically rolling admissions, but still. Ah well, another bump in the road we (hopefully) won't remember in a year lol
