We've noticed that occasionally the IG API is not including recent posts for a short period of time.  

We do cache images on our side to make it so you don't run out of IG requests, but the longest that could possibly be right now is 3 mins. If you don't notice an image showing up, take a look at the new refresh button we have in your dashboard http://linkinprofile.com/dashboard to make a request of IG for updated images.  

Please use this button sparingly as you can exhaust the limit that IG will allow for requesting new media. 

Should the image still not appear after the refresh minutes, please let us know and we will dig deeper.
