Skype freezes when attempting to answer or make calls

After the most recent update, skype has been performing mediocrely. When I answer a call, it freezes for five seconds and then the entire app shuts down. When I try to make a call, same thing happens. Might as well be making the usual phone calls without this happening. Also Im using a iPhone 6, so its not out of date and the skype on my iPhone 4 still works better than my iPhone 6.
