Hello Dude,
Hope this message finds you well, the organizers has fixed the technical issue and now the report submission is working, I just submitted my report online (You may just select the options in the forms and write a description paragraph for whatever you have done in this competition, the attached document report is only optional, not a must).
for those who still could not see the website, please just clear your browser history, then refresh it.
and of course I am not onbehalf of the organizers committee, I just shared my experience with you and for your reference only.
Hope it helps.
All the best wishes for your final ranking.
@Organizers, thank you so much for your efforts behind this competition, highly appreciated.
Thanks and best regards
David
