• Maintains consistent campaign delivery
   

Invalid Player Request Safety

3) Bug Fixes

1. Deal Name Not Displaying on Inactive Line Items

Issue: When editing a line item for an inactive deal, the “Deal” field displays only the deal ID instead of the deal name.
Fix: The “Deal” field now correctly shows the deal name, regardless of the active/inactive status of the deal or line item.

2. Playout Still Active After Frame Mismatch (SHELL Players)

Issue: Playout continues even when the frame in the slot does not match the frame in the screen layout. Editing the frame does not resume/stop playout unless the player is reopened.
Fix: Playout behavior now correctly stops or prevents playback if slot and layout frames do not match.

3. Beta Tools Page Access Without Permissions

Beta tools page accessible for every user regardless of system role

4) Impact & Risk Statement

• No downtime occurred during deployment
   
• No client action required
   
• Existing campaigns, line items, and integrations remain unaffected
