Ifunny won't sign into twitter account?

So ifunny automatically logged me out of my account and usually it just logs me back in but for the past month it just kept loading then stopped, and then went back to the home screen. I don't understand because it works on my ipad. It's on my iPhone btw. T I've tried uninstalling and reinstalling and then turning my phone all the off then on but it still didn't work!

It Could Be a Problem With Ifunny On the Iphone This May be Something iFunny Needs to Fix you may Not Be Able to Fix this
