When should I switch physical therapists if my therapist seems distracted?

I’ve been going to physical therapy for a couple weeks now. The physical therapist I don’t feel fond of. When I check in he has me start the exercises right away. I thought normally they place a heating pad on the area before they get started. I saw another therapist once last week because he was out and they automatically applied the heating pad. After that session they asked if I wanted ice pack or heat.
Fast forward to last Friday, I was back with the same therapist. He was working on two other patients besides me. When I got done with one exercise I had to wait for him because he was on his phone looking up a football player for another patient.

I forgot to add also when I had the other therapist I made appointment with them for this week trying to get away from him. I found out when I checked in that he changed it back to him.
