No, I haven't received anything yet! My online SGS application is still showing that my official transcripts are still pending, though my tracking shows it's been long received. I believe they are extremely overwhelmed with processing a huge volume of applications amid the COVID19 strict safety measures that they should abide by.
But it's good news that they keep processing applications till the last minute! Sure, you should be considering alternative options, yet don't lose hope, no body knows!!
May be we would be in the same cohort, since I too applied for the J/I (Math) !!?
