The spots are brownish and expanding slowly. They seem crispy but the same thickness as the rest of the leaf. I want to catch any problems early because she’s still new to me.

Do you think it could be a slight sunburn? That’s slowly getting more burnt? I’ll check mine out in the sunroom and gets pretty hot out there. I’ll see how it looks new plant to me as well
Ok just checked mine and I have about the same issue 
And mine is extremely dry. There’s no water around the ring and the soil needs watering mine could definitely be from heat & lack of water. Mine sits about 2 foot from the roof & about a foot away from the window, so it does get some sun, but not much.  so I’m going to water it & put it back in the same spot & I’ll let you know.  not sure if my information will help, but hopefully it will be useful. 
I’m having the same problem with mine as well.
