At least, it's their policy:
Just so you and everyone else is aware, we have the policy of not monitoring CJ feedback on any external (to Google) forum. If you or someone you know has feedback that can/should be actioned, please ask them to either use this list or contact us privately at [email protected]. They can also use our social channels, but it's a less efficient form of communication for system-type feedback.
So, it you have a technical problem during the upcoming Qualification Round, rather than posting it here on Codeforces, email it to [email protected]. Or do both.
Then let's discuss the problems on Codeforces during the contest xd
If you get "Sample Failed: CTLE" don't hesitate to submit the same code again. It seems that the judge is not that stable yet and gives different responds to the same code.
Not only the judge is buggy :D
I am getting CTLE while submitting a past problem. Can you tell me the reason why this actually happens?
If anyone wants to participate via last year's interface, you can do that here.
Now this where I melt....
I'd like to, but it seems link doesn't work. I had problems using Firefox: verdicts doesn't update properly and scoreboard too. I've wrote this during qualification round, they answered me, but during Round1 it was the same. Has anyone same problems?
They disabled the old UI before round 1B, probably in response to my message. So now using the new UI is the only way to participate. I also encountered verdicts that don't update (a submission is shown as "pending judgment" forever). If this happens, just reload the page.
Unfortunately it does not help. Sometimes after a long time (10-20 min) it shows verdict, but even not for every problem. I can not see a regularity.
Interesting that they answered that only from me they got such issue.
