Fix for the "Unable to start chat: Cannot update issue property com.spartez.supportchat.last.seen" problem
When starting the chat, and also during the chat's message exchange, several issue properties are being updated. This cannot be done in the context of any of the chat participants, so the user account used to update these properties is the project lead. Therefore, it is crucial that this user has the following permissions in your project's permission scheme:
Edit Issue permission
Browse projects permission
Access to the project's Service Desk
See the Jira documentation for more information on how to set this permission.
