+       Native mid-circuit measurements and conditional operations (using
+       :func:`~.pennylane.measure` and :func:`~.pennylane.cond`) are not
+       supported by ``default.qubit`` in simulation workflows that require
+       gradients or specific state preparations dependent on measurement outcomes.
+       For simple sampling workflows, measurement may return values, but
+       dynamic circuit execution is limited. Consider devices explicitly
+       supporting dynamic circuits if required.
