If the Interleave default isn’t enabled, then the default layout would need to be scheduled for it appear on the screen when other layouts are also scheduled.
Which CMS and player version are you using please?
We would need to see a screenshot of status window then please.
(Press i on your keyboard to show the status windows while Xibo for Windows has focus).
You can also check the schedule.xml file and see if it has the content it should - you can also double check CMS Schedule page Agenda view to ensure default layout is not scheduled.
I assume the default layout is layout ID 1?
If that’s the case, then it seems to be in the schedule, from the looks of it either as interleave default or with always daypart.
Or is the default layout with different ID that isn’t on the list there? In this case I’d not expect the player to play it.
