Calendar doesn’t have option to share.
After I updated to the IOS 11.1.2 the GPS on my phone could not find my location. I went into the store and they recommended resetting my setting, which I did, and it solved my GPS issue but now I do not have the option to add people to calendars and the calendars I had formerly shared with others are no longer shared. Not sure if there is simply a “make calendars shareable” setting that I need to reset but I would like to avaoid resetting again if at all possible.
