Tickets can be viewed on V2 Client Screens, as well as V3 Accounts under the Activity Stream:
Like the V3 Activity Stream, Tickets will need to be selected under filtered items before they'll appear in the Activity Stream. Any time you make changes to the filters, they will stay for all Accounts until they're modified again.
The cards in the Activity Stream will display the Subject, recipient email address (if applicable), Ticket number, email status (if applicable), timestamp of the last update, assignment, and the first line of the body of the Ticket:
Click any card to view the Review Ticket Overlay. Clicking a Ticket card will open this overlay in a new tab over the Tickets Screen. If you don’t see the new tab open, be sure to check your pop-up blocker.
