Hi JOSE003!
1) Please don't write with gigantic letters =)
2) I think after a few days is still fine, but it would not hurt to PR it again))After all it is just 5 minutes maximum
3)There is no need to PR 2-3 times
4)You will go over the trigger words during preview or postview, but also when you are activating.
Best wishes,
