I submitted same day as well and I see OCI application acknowledgment dated today.Applied walk-in on July 25th at Brampton and today is the 8th business day. It still says 'no records found' on the OCI site. Hoping for update later today. If not probably mid week next week. I have seen recent updates here where two of applicants status was updated on the OCI site exactly at 8 business days of submission at BLS. Fingers crossed.
