I would like to make a general statement as an advice or a general truth. Which tense should I use in these sentences?
The term “No problem“ used after someone (says)/(has said)/(said) thank you.
If someone (says)/(has said)/(said) something bad about you, forget it and keep moving.
When we take our devices into bed, and see new likes on a picture we just (post)/(have posted)/(posted), this causes the release of another chemical in our brains, dopamine.
It seems the AE accepts to use simple past for these sentences. But BE only accepts present perfect or present simple. I still confused.
