For all those are wondering about status change to "Application Received".
"Application Received" is the first status which you see under "View Submitted Application" tab, earlier there were only this tab and whenever anyone submit their only application, they get "Application Received" status. "Summary of Application" tab was recently added by SINP they mistakenly put status as "Received - In Progress" which was equal to "Application Received" .
Now since they have corrected their mistake and synced both tabs status, your status is showing "Application Received" in both tabs, which is correct and No need to worry about.
The next step will be "In Process"( From date they start working on application until they request other documents.)
