Hi, Hitesh
you have extended the Deadline to Thursday, June 7, 2018 UTC
but on designers' side Project status looks - Closed (Pending Selection) thus new designers can't submit their ideas

Maybe you see project status as "Open - Deciding" from your customer account
yet if you put (+enter) contest link in browser not being logged in the account -- then you see - "Closed (Pending Selection)"

Hi,
do you see "Comments and Questions" section?
