best filler for Cathedral Ceiling crack?

Good afternoon.
I would appreciate any feedback regarding the best way to fill a long crack on my cathedral ceiling. The crack runs the length of the line where the flat middle of the ceiling meets the angled north side. Twenty feet is a noticeable crack! The room was built 3 years ago and the contractor has filled the crack twice, but I don’t recall with what. The crack came back a few months later each time. The ceiling is unpainted. I assume the cracks come back from slight movement of the house.
thank you.

Nothing will fix it unless you put a wood piece at the angle to conceal the crack. Strait-Flex makes a metal product called X-Crack to eliminate this problem; I went to their website but no info on it. Only way to avoid it recurring is to remove the boards and use the X-Crack.
The cause of this is that on the angle their is no wood backer for the sheetrock and with the wood shrinkage, difference in temperature from the inside to the outside causes the wood to shrink and then the drywall angle cracks.
Flat middle meeting a slope sounds to me like the structural ridge ebam is part of the finished cieling, barely covered. Need photos to be more certain, but if that is what it is, this will continue indefinitely and probably needs a false beam hiding it. The dissimilar materials move at different rates from heat and humidity and settling. I suspect he used no strapping to bridge this cieling.
