Solution: Please add support for teams that are able to access the tickets that were created by all members of the team. This will make it much more easier to collaborate during the daily supporting tasks.
Background: Currently only the opener of a ticket is able to access and work with his own tickets. Using the Cc option is limited and unreliable. Cc can only be added after creation of a ticket. And Cc does not work every time (for unknown reason). And attachments or embedded screenshots will get lost in most cases. All this makes it much more complicated to collaborate during daily supporting tasks.
