M31s Fast Charging not working

[MadeInAM]

After the latest software update, my M31s have been malfunctioning while charging. Fast charging doesn't work. It's always cable charging. Fast charging only works when I restart my phone, otherwise it doesn't. 

Anyone else facing this issue and if anyone have debugged this?
