Going to our favorite source, Flightradar24, we tracked the two operating MAX8s.
The second aircraft recently arrived at its home base (KUL). It has not been put into service since its delivery flight. But the first aircraft has seen its hours jump. This suggests the aircraft is doing its job with few, if any, mishaps. The data suggests that 9M-LRC was averaging 3.4 hours per day in May. To date in June it averaged 1.6 hours daily. In May 9M-LRC was used regularly between KUL and NRT. In June it seems to be doing KUL-India and Pakistan.
