Shared notes not synching

I’m not sure when exactly it started, but at least two updates ago. Currently running iOS 16.4 on all our devices (entire family). We use shared notes between family members for ongoing lists and they do not stay up to date. The notes show that they are shared with the image of shared individuals on the top of the note. They share once then don’t update when changes are made. We’ve deleted notes and started new ones to replace…still same issue. We’ve force quit, rebooted, checked sync status toggle in iCloud settings…nothing helps
