This is a great template and highly useful for communications around COVID-19 (and other issues in the future!). We set it up with everyone having read access but did find a weird problem. The menu links can be edited from anywhere in the site and usually point to a page like /sites/crisismanagement/SitePages/pagename.aspx. For some reason that I haven't figured out yet, sometimes they're getting changed to a link hanging off of /_layouts/15/guestaccess.aspx. I'm assuming it has something to do with sharing the page out (maybe?) but it changes the menu link and in many cases the link becomes invalid. Like I said I'm not sure what actions are causing this but it's happening with a site where only a few users are owners and everyone is a reader. I'll post more info if I find it but something to watch out for.
