I was writing my solution code and participating in the contest (Codeforces Round 1104, Div. 1 + Div.2) on my mobile because I didn't have access to my laptop at that time due to some reasons.
While writing the code, just when the solution clicked and I had finished coding, I clicked on 'Submit Code'. . . only to be greeted by an endless cloudflare verification loop check despite being a human and having a stable internet connection. With each passing second, I was sweating. Finally, after switching multiple tabs, refreshing the site, and entering the contest again, I was able to submit the code.
Though this round itself had multiple technical issues, I had also experienced this endless verification loop earlier while using Codeforces on mobile during my university classes. I've also sometimes noticed slow problem loading responses on my laptop.
I don't know whether it's a server issue or whether ignored factors like many unrated bot accounts that claims to have solved thousands of problems and appear on the standings; might be contributing to the verification traffic.
So, I wanted to ask; has anybody else experienced this? If so, what was your solution to deal with it, or is it just me?
Also, it would be nice if Codeforces could add an automatic problem code filler during submission, as it could save a bit of time and be helpful for the community as well.

Me too, got stuck before submitting D. I had to wait for about 2~3 minutes.
Yeah, im also experienced it. To avoid that kind of problem, I use site to read problems and submit code for contests,this site works only during contests
I don't have any idea why that happens sometimes, but it is indeed kind of annoying,
I remember in the last contest, I submitted the code and then switched the tab [it was a re-submission, as my code failed because of Integer overflow] and came back after some minutes only to find that it was not submitted, not that it was catastrophic, but still its annoying!
There was a div2 contest, where I solved E and couldn't submit because of this issue. Although I had 2-3 minutes left, still it wasn't enough to verify that I'm not a robot.
respect to bro, who coded on mobile and still get positive delta.
