While it’s true that Dorico does not correctly playback a repeat structure like this when the repeat marker has the Replay repeats property activated…
…the development team is aware of this and will eventually commit the resources to fix it. In the meantime, correct playback can be achieved by selecting the first ending bracket in engrave mode and setting the following properties:
- No. times played to 3
- Times played for segment to 1,3
- Custom text to 1.
