Iphone 6s Calendar not connecting to the internet
I am using a IPhone 6s version IOS 11.2.2.
My wife and I share Calendars with phones and computers. I am able to see my wifes calendar events on my phone and my computer. She cannot see my events on her calendar. My computer is also not seeing the events that I have put in on my phone.
When I open my calendar, on my phone, and click on the word "calendar" at the bottom, a page pops up with sharing and viewing options. Under the top box it states, " Unable to connect to the internet". My guess is that this is problem. There is nothing I can find that can change this.
Under settings>Icloud, it shows that I am sharing my Calendar through Icloud.
All of my other apps seems to working properly and connecting to the internet.
Thank you for any help,
iPhone 6s, iOS 11.2.2
