i have confusion with adv I have been confuses/I was confused. recently: we can use the word with both times. Then how to understand the sentences: I saw him recently. I have seen them recently.

The word 'recently can suggest: 1) not long ago and 2. during the short period of past time extending up to the present moment.

If we see it as #1, which is more common in AmE. we use a past tense. If we see it as #2, which is more common in BrE, we use a present perfect.
