I can add that the USA Today app just started working. Again, this is something listed in your standard News apps available.
I have no idea what the RSS feed is. This is one of your own apps. In fact, it's listed in your 'Essential Apps' section (near bottom-right as "Yahoo! News".)
The Yahoo News app seems to be acting up again. Most of the tabs are now picking up virtually no new news, whereas the Science tab is getting more than normal. Normally, the main World, US, Politics and Technology tabs would have 100+ messages when I checked in the morning. Now, beginning Feb 17, they only have 3-4. Many marked February 16 were actually several days old. Also, it's not properly decoding some code, so, for example, the apostrophe " ' ", is showing as "'"
As for July 9, this seems to be fixed.
At least in APP mode, modules with multiple tabs no longer allow you to clear the unread counter by clicking on the gray number next to the title. This is similar to the mail apps change that took place a number of months ago.
I also had an issue on one app (NBC News) where clicking on the red unread for a single tab would not clear the unread, except for the first tab.
As of this week, it seems to have cleared up.
As of 5:30PM, the World tab now only goes back to 1:12PM (about 26 entries.)
I have been seeing this on Google News widget, when set to open on original site, and using Firefox. Internet Explorer seems to work.
