This is explain the best I can, on how to use dev tools when your in a tounament. Now I just finish a tournament so my ss is gonna be probable some what vague or hard to understand but i will do the best i can to explain. This using Google Chrome.
ok here I go
Press F12 to open dev tools.
Expand dev tools so you "Network" across the top. Click on "Network".
Now to want to check the "Preserve Log"
as you can see there is alot of things listed. just click on one and go through it .
4. Click on "Results"
5. Click on "Message"
if you click the up arrow it export a file (.har) which can be sent to mods. for review. (sorry forgot to mention earlier)
Do that for each item you have in the left hand column, and it will tell you what was going on.
I sure hope you all understand this, or if any is able to simplify it even more please feel free.
