Messages not working
Hi I am having trouble with messages. The app will not open and will instantly close upon launch. I am on iOS 10.2.1 however I cannot update my device either. I have an iPhone 6 Plus, so that should not be a problem, but it keeps prompting me that an error has occurred downloading IOS 11. I have tried restarting and many other methods recommended by other supporr users. I still have no solution and I don't know what do do at this point.
