Aptx adaptive support on Xiaomi 11T???

I have a problem with Xiaomi 11T. There's no aptX Adaptive codec present. My "haylou w1" connect without a problem using this codec (aptX Adaptive) to Mi 9T pro, but with 11T there is a problem - it connects only by aptX and when I select aptX Adaptive in developer option it has no effect and stays in aptX. Is this a bug in the firmware or did Xiaomi remove the codec on purpose to make the phone worse compared to more expensive versions
