Multitouch is not working for triple touch or above

I have referred one of the [https://github.com/AirtestProject/Airtest/blob/master/playground/android_motionevents.py](url) GitHub for multi touch events. But only up to Second finger is happening. Triple touch or above not working properly.
Kindly provide me your suggestions to perform triple touch for Android and IOS using Airtest functions.

# 1. tap with three fingers
multitouch_event = [
DownEvent((100, 100), 0),
DownEvent((200, 200), 1), # second finger
DownEvent((300, 300), 2), # third finger
SleepEvent(1),
UpEvent(0), UpEvent(1),UpEvent(2)]

dev.touch_proxy.perform(multitouch_event)
sleep(1)
