My fiddle leaf fig has finally stopped dropping leaves after I moved it away from the radiator

My fiddle leaf fig has finally stopped dropping leaves after I moved it away from the radiator. Took me two years to figure that out—I was convinced it was root rot or light, but honestly it was just the dry heat. Now it's putting out new growth consistently. Anyone else had stubborn figs that suddenly turned around once you fixed the environment rather than fiddled with watering or fertilizer?
