Notes on my Fiddle Leaf Fig

I've had my Ficus lyrata for about three years now, and I finally figured out why the lower leaves kept dropping—it wasn't underwatering like I thought, but inconsistent light and temperature swings near my window. Since I moved it slightly back and away from the cold draft, it's been putting out new growth steadily. The leaves are still smaller than I'd like, but I'm patient. Has anyone else struggled with leaf loss on theirs?
