'I just received' or 'I have just received', which is correct?
In my opinion, I would suggest that 'I have just received' is the grammatically correct statement. The reason is because the phrase is using the adverb just which is in present perfect tense.
They are both correct. I thing they are in different tenses...past, present, etc.
'I have just received' is a correct expression cause an adverb 'just' is used in present perfect tense.
