Failed to Submit a False Positive

I have already  tried three browsers which are google chrome, edge, and firefox. None of them showed any progress.
In the webpage, when I clicked "submit" button, I waited and waited, and then it would ask me to recheck if I was a robot, and then told me to try it again.
Please give me an email address to sent the sample files. It's really urgent~

Hello Skylar,
Please submit the files in any alternate browsers and you can upload the files on upto 50 MB of size with no issues.
Upon a successful submission, a group of analysts will review it and whitelist (if there is no malcious content).
Keep us updated on the progress.
