Trick I found and that has been successful for me most times is to go to "What's New" for a category, click page two, click page one, and then I have the latest update. Worked for me the past couple of days now.
I've "spammed" ctrl+f5 more times than I can count and it never updates. Not in Firefox, not in Chrome, not in Edge. Refreshing worked a time or two well over a week ago, but hasn't since.
