For some time now my Samsung Note 3 has been sending out updates or invites (depending on the action taken) whenever I add or change an appointment on my calendar that is tied to someone. I do not want a notification to be sent, but it is an automatic. I can turn this off in Google Calendar to where it asks me and I can decline so it is not a problem from Google Calendar, but only from the Android calendar when I move the time or date and when I create a new one with a linked contact it automatically sends the invite or the change. Please advise on how to stop this from happening. Thank you.
