Headings have issues with creation / dragging
Planned ResolutionProblem
Headings are problematic when first created. They sometimes don’t always maintain position, or remember which tasks you drag into them.
In the meantime
After a Heading is created, just leave the list and come back to it. That’ll force-refresh it and it should work relatively well (dragging to rearrange headings is still problematic).
Planned resolution
This will be resolved in an upcoming software update!
