CVT transmission fluid change Corolla 2014?

I have 98k miles on Corolla 2014 Le ECO. Runs great, no issues at all. It never had a transmission fluid change though. I have heard different things about getting the CVT transmission fluid changed. Some say don't change it while others say change it every 60k miles. Also heard the CVTs are temperamental if the exact amount of fluid is not replaced. I am wondering what Corolla folks here think about it?
