True, mine changed to Oct 4th. IRCC probably is working on fixing this glitch because when I reached out to IRCC yesterday, they said they are not expecting any document from me.Hi @Harshas114 , as stated by @RSub this is a glitch for sure. Now the 'Required By' date has moved up by a day in my portal. We should ignore this as this is coming under optional documents anyway. I Hope IRCC fixes this in their next maintenance window.
