I used to be able to set compare_at_price to null after a product was on sale but now I get an error
Price was: 1000, Compare at 1200
I want to reset it the Price to 1200, with compare at 0.
(422 Unprocessable Entity) compare_at_price: Compare at price needs to be higher than Price
I can neither set it to 0, so how will I disable the compare_at_price to 0 or null or remove it?
