Hi Edwen Kerk, I am writing a function to logout previous user, I have followed this your post At the remove ticket line, I use the command: var ticketIds = this.TicketManager.GetTicketIDs(); to get a list of ticketIDs but always return null. I am using sitecore 9.1 update 1. My question is: Does Sitecore 9.1 support to use this method?
