Is there any way to get My Updates Liste them further back than just 1 day?

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

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