Not working properly

I am using iphone 5s using the most updated iOS10 and this app is not working. If i double tap the frame that i would like to use it kicks me out of the app and goes back to home of my iphone. Please fix it maybe the app needs upgrade. I always use this app for IG and i love this app. Please fix it.
