If you updated here on Marketplace, the update approval email or notification you got, then yes buyer will get new updated file when they download again.
But if your update is pending in Edit - Advance Setting then buyer should have to wait until Codester Team approve your Item Update.
No, its not possible because buyer can download code anytime and they get last updated code.
So, if the issue is they still getting old files then Frederick should have to know, it seems like a bug.
Hello Frederick, please look into this matter asap.
