"error - rate limited. please try again later" what does this mean, ive been trying to do it for a while (also sorry if this is common knowledge this is my first time actually using speedrun.com)

I don't know what it is, but I think it's something with how many runs are submitted, just try it today... idk

it was because the run was 30 minutes long (5 min longer than the max amount) so nvm

oh ok

It's possible that as new users, we can only submit a certain amount of runs per day.

That's something I've been finding as well, was thinking maybe due to being a new account but wasn't sure.
