same here. Same thing as noted above.

I tested the system but reinstalling it on Wednesday and then viewing as normal until today. Currently it says I have 9 notifications for articles I can not see. They are : 

*CNBC : AT&T PAid Trump lawyer Cohel up to $600...
*Centurylink (CTL) Q1 2018 Results
*Avaya Holdings' (AVYA) CEO Jim Chirico On Q2
*Enbridge Inc 2018 Q1 - Results - Earnings Call
*Dominion seeks approval for North Carolina
*Engaged Capital udapes on portfolio hodlings
*Paulson added Goldcorp, exited Oasis Petroleum

The article itself does not seem to be the issue but that for some reason some will not be viewable in the notifications tab. And these sit and other build on that. 

To reiterate. I see the article in the notification on main screen of the phone, but when I go to the App they are not there under the notifications tab.

I am still having the problem. it is happening more frequently. I have uninstalled and reinstalled a few times to reset the counter and in a day or so the same thing happens.
