We use DayPilot with React.
We wanted to use the new yearly scheduler together with multi range. But when we use the mutirange.add function for dates not in January we get an Error:
Error: Time range selection 'start' out of timeline
I confirm the bug. It will be fixed shortly - I’ll keep you updated.
This bug should be fixed now in the latest sandbox build (2025.1.6338).
For now, a range that spans multiple rows will be limited to the first row when added using multirange.add().
