iPhone Calendar won't sync with Mac
IOS 16.1.2, Ventura 13.0.1. I sync my phone with macbook using the cord. I noticed the calendar stopped updating on my phone; neither devices update each other. I don't sync thru icloud, i've looked at loads of forum responses about toggling options, signing in and out, restarting... I tried to force update the phone's calendar in the 'advanced' options section, 'update phone from my mac' at the bottom of the info tab - that doesn't force a change to the phone. I don't know what/how this randomly 'broke'. Thanks for any help about what this is and if there's something I can do.
iPhone 11, iOS 16
