Mail 'fetch new data' completely greyed out
Hi, recently purchased an iPhone SE, upgrading from my iPhone 5s. Everything was working fine on old phone, then restored from a back up. The only issue I've had is that fetch new data (gmail) is completely greyed out. I have tried rebooting and ensured that all restrictions are off. Once I click through fetch new data absolutely everything in the next screen is grayed out. ideas?
iPhone SE, iOS 10.0.2
