Hey, ITA is the date that you received the invitation to apply I assume. I think in your case 19th july was the date of submission of your PR application So your ITA must have been earlier. UnderstandableI had submitted ITA at 19th July 11:25Pm and 11:30 to 5:30 AM was maintaince as well and morning I got AOR
Or maybe you received it and were fully prepared man either way all the best
