Error message

Ali • Married to my Best friend and soulmate, 3 children, and recently found out we've been blessed with #4 due May 2016!!
I receive the notifications of new comments and whatnot but for awhile now when I go to click on the notification to take me to the new comment, I get an error message stating oops unable to fetch post and never takes me to the comment so I'm never able to see it. It says try again later but it doesn't matter how long I wait it never takes me to my new comments. This started awhile ago here and there but now it's happening more often than not. I love this app and would like to know how I can fix this! I saw another post not too long ago, another lady was having the same problem and getting the same error message as myself. Thanks in advance!
