My iphone is iPhone 13 Mini. iOS version is iOS 15.1. Instruments version is 13.4 (13F17a). I can get thermal state with iOS 14, but it's only unknown thermal state with iOS 15. Is it not supported to get thermal state in Instruments under iOS 15?

As the documentation says, Limiter counters tell you which subsystems of the GPU are active by providing a percentage of the total number of processor cycles during which this subsystem was active. Besides, Instrument also provides some Utilization Counters and the value is different from the Limiter. What do Utilization Counters mean?

My XCode version is 12.5.1. It seems to only support iOS 14.5 and before.
