Hi Everyone, I have been using Arylic S50 pro plus for a month now. Pretty new to the device. Sorry if my questions have been discussed before,

I need support on 3 points

  1. Is the firmware 4.6.415145.35 is the latest firmware for s50pro plus?

  2. How this device get updates? is it automatic or do we need to manually do something ? I couldn’t see update menu on the phone app

3)Are the devices manufactured 20220427 and onwards supporting up to 24 bit 192 kHz sound output ?

Appreciate if anybody shares information about these points, Thanks
