Contacts found on servers works for one account only
I have connected my mac to two accounts: a google and a windows account. When I create an event on Apple calendar under my windows account, calendar displays the contacts "Found on Servers", as well as those "Siri found in Apps". However, if I create an event with my google account, calender only displays the contacts Siri found in Apps.
