Lack of empathy from new T

My last therapist left practices a few months ago so I’ve been seeing my new therapist for over 3 months now and I can’t help but compare the empathy I felt from my last therapist. Sometimes when I share something very vulnerable she doesn’t say anything to validate me or indicate empathy she just nods and makes an “empathetic” facial expression but that’s it. She doesn’t acknowledge what I shared and just follows up with some questions. They both know how I struggle with vulnerability and my last therapist knew how hard it was for me to share these things and would always say stuff like “yeah I can see how that would make you feel __” “thank you for sharing that I know how hard it is for you” or even saying “It’s valid to feel that way” and she would have this empathetic warm tone where she would speak a little softer and slower which made me feel seen and indicated that empathy to me. Could this be a difference in their therapeutic approach or just incompatibility?
