Just went to CW for covid extension--first off props to IB for the new app-based queue system. Very efficient, good going guys. One thing I noticed is on my stamp it has Nov 25 at the top as expected but there doesn't seem to be a close loop return date line. It's seems to be the date line for the officer's signature. And sure enough, it has today's date stamped in. There are no other written or stamped dates. Is this an error? Could they have used the wrong stamp? Or have they stopped requiring the close the loop trip and I don't need to go back until 25 Nov? Thanks
