There is a bug in the latest iteration of IG Beta, actually two of them. The first one is when you go to a picture of yours, then your multitask out of the picture to another then it seems that the IG app closes. Anther bug is when you get a live tile notification, and when you go and see what like you have, by refreshing and you go back home, then the banner is still showing that you have notifications even though you have already check the application. I was trying to contact IG via email but I could not find an email just a website and help page that did not have what i was trying to explain to them.
