  In recent breakthrough experiments, twisted moir\'e layers of transition
metal dichalcogenides are found to manifest both integer (IQAHE) and fractional
(FQAHE) quantum anomalous Hall effects in zero applied magnetic field because
of the underlying flat band topology and spontaneous breaking of the time
reversal invariance. In the current work, we critically analyze the
experimental values of the quantized conductance in each case to emphasize the
role of disorder in the problem, pointing out that obtaining accurate quantized
conductance in future experiments would necessitate better contacts and lower
disorder.
