I phone 7 plus can't delete any apps
I have a 7 plus that I bought in September. About a month ago I wasn't able to delete any apps from anywhere. I brought it to C Spire where I purchased it , they tried a few things and it still wouldn't work. They said they have never seen anything like it and said that I should contact apple. So here I am. Can you please help me?
iPhone 7 Plus, iOS 11.0.1
