* don’t repost your patches within one 24h period

We have already told you one of the fixes is wrong, but you did not
wait 24 hours, so have not see our feedback.

Also, in general when using a tool, assume it is wrong, and convince
yourself it is correct, before making a change. "The the in this
sentence is the subject." What does the bot make of that? Can you
convince yourself the bot is correct?

"Later on" is an established English expression. A plain "later" also
works. This isn't a correction of an error; it's a stylistic change.
