Thanks for reply.
I just checked by loggin in to my ACS account and tried submitting the new application,I could see that they have indeed linked the previously submitted documents all details in new one.
Also the change I could see it that document should be scanned in 300 dpi format.
Last year I uploaded documents with 200 dpi size.
Is there any other change to the process that needs to be taken care?
Can you clarify if you know ?
Thank you again!
