Is 24 weeks too late for anatomy scan ?

So we recently got medical insurances after issues with it at the doctor that is closest to my home . Today I had my first appointment with them I went to another clinic for my first 2 appointments at 8 weeks and then at 12 weeks but today Im 19+2 and I taught the would do my anatomy scan along with the appointment since they do it in the clinic but the doctor said that I will be having mt anatomy scan until I’m 24 weeks I heard it’s best at 18-22 weeks and baby on both ultrasounds at my last office was measuring on track not a day behind or ahead. I don’t think I will be waiting that long for anatomy scan that is insane should I switch doctors ? I’m thinking about making an extra 15 minute drive to the office I was going to instead

They said they can’t do it before because they don’t have space on the schedule until I’m 24+6
