Why do I see multiple events in Salesforce1, but not on the Full Site?
|Knowledge Article Number||000194176|
I am able to see multiple Events for a record on Salesforce1 where as there is just one Event for the same record when checked in the Full Site.
|Resolution||This happens if there are multiple "User's" listed as "Invitee's" and they are the subordinates of the affected user in the role hierarchy.
"A user can normally view all records of their subordinates in the role hierarchy, resulting in multiple copies of an event appearing when someone invites someone below them in the hierarchy."
