…Profiling is false Transaction-based profiling (profilesSampleRate/profilesSampler) always relies on the legacy Debug-based profiler and is not supported by the ProfilingManager (Perfetto) backend. Previously enableLegacyProfiling only controlled continuous profiling, so profilesSampleRate + enableLegacyProfiling=false would still run the legacy transaction profiler. Now setting enableLegacyProfiling to false also disables transaction-based profiling on all devices, logging a warning to guide users towards profileSessionSampleRate for continuous profiling.

Summary

enableLegacyProfilingso that setting it tofalsealso disables transaction-based profiling (profilesSampleRate/profilesSampler), not just continuous profiling.Why
Transaction-based profiling always relies on the legacy
Debug-based profiler — it is not supported by the ProfilingManager (Perfetto) backend. PreviouslyenableLegacyProfilingonly controlled continuous profiling, which led to a confusing combination:Per discussion, it's sensible that
enableLegacyProfilingdisables transaction-based profiling too.Changes
