Ceiling light lag/delay physical switch on

on top of this, i read through the forum, it seem i’m not the only one facing this issue? below are also people having this issue. the physical wall switch is on but no light from the LED light, wifi is offline as well.

i’m in singapore, do i have to provide my ID here too? please let me know soon because i’m getting a contractor to come over my house to inspect on the wire connection, i have another spare light to test it out but i hope it’s the last resort as there will be fee incurred for doing those mounting and unmounting.
