Improved Tessitura Sync Settings Control and Messaging

Changing sync behaviour for a single performance used to ripple across the whole season. Tessitura sync settings now support per-instance custom attribute overrides, clearer connection-state messaging, and safer handling for inactive controls, so teams can tune a specific performance's sync behaviour as an exception rather than changing the global sync map for every event.

Per-instance overrides

A single performance that needs different sync behaviour can now be configured independently without affecting the rest of the season. This makes it practical to handle edge cases, such as a performance with a different mode of sale or a specific attribute exclusion, without bespoke workarounds.

Clearer connection states

When a connection test fails or a web mode of sale is inactive, the admin now shows a specific, actionable message. This makes Tessitura configuration safer to review before a season goes live.
