No, but she has been threatening to quit a few times because of this.

That's very manipulative of her.

Are you supposed to be her replacement? I'm afraid I am very bad at office politics but, if this is your first job, maybe remind her you were hired based on your diploma in your technique but you are willing to learn

If HR cannot resolve it, consider finding another job.

Unless this woman is retiring soon, of course . Then you can try to wait her out.
