It is all speculation of course, they have had the last day of the week as "the week of" date as well, which wouldn't make sense at all if it was "the first day"Yes thats why i think that 15th or 16th when they mention that, its the start day of the week, so if they mention they are working on 16th Sep. week, this mean from 16th to 22nd , thats my understanding.
They are just behind on sending Aug/Sept/Oct AORs. I do see a lot of online apps getting them recently.
also if you check the new tracker website for citizenship apps: Canada citizenship tracker / Suivi de la citoyenneté canadienne (cic.gc.ca)
It says the week of Aug 8.
