Sony mx4 firmware broken feature headphones

[steelcork]

Updated latest firmware on the mx4 headphones on 7th November , now the auto power off isn't working and the battery will die unless you manually turn it off. I've done a factory reset , the firmware has messed this up also no option to change the time interval on the latest Android mobile app. Was working before the latest firmware update. Now its not

You did a factory reset of the headphones.

Did you update to the latest version of the headphones app as well?

That's the command room of your beautifull XM4's.
