OK, some follow-up on this matter. I just downloaded my archive again and the archive tells me that my account made 36 tweets. But my account is still showing 463 tweets on the profile page. I am not sure why this irregularity exists, but it seems that this number of total tweets is not updated correctly. Maybe it’s a bug, maybe it’s on purpose, I am not sure.
Is there a way to open a case or ask an official Twitter resource why this happens and if it is intentional?
