just open in another broswer and try

I also face this problem but don't worry about it it's  just a technical problem,

just try it in chrome incognito window

I tell you, just open the chrome and now press the key -------> {Ctrl + Shift + N}

and then there will another window open and just go on jossa site and try again.

Thank You

Have a Good Day

i have just downloaded my sit allotment letter for round 2. you may also try it now.
