Is there any way to get My নবীকৃত তথ্য তালিকা them further back than just 1 day?

It's not the last day; it's just the 100 most সাম্প্রতিক নবীকৃত তথ্য (pages 1 - 5, with 20 to a page). Depending on how many সংগঠন are in your তালিকা and/or what নবীকৃত তথ্য filter আপনি use, that could be anything from the past three months to the last ten minutes.

In general, আপনি get a তালিকা that goes further back if আপনি use the drop-down filter. For instance, আপনি could sort দ্বারা "Articles" and probably see a lot further back than, say, "Picks" (and certainly further back than "All updates").
