I don't think you miss BIL request on mail as in that case the same message would be reflected in your GC key too which is right now having only 2 messages. For FSW-O candidates, BIL is awaited after 21/Sep. I guess for CEC too the processing times are getting slower.
You would be surprised to find cases of missed BIL, RFVs, etc on this forum. IRCC might be adjusting back to the normal processing times from the extremely fast times we saw for the first half of this year(which was unsustainable as they were/are 65% overstaffed).
