This firmware update is being rolled out in stages, with devices updating sequentially over the next few days.

Alexa: Fixed a login failure that blocked account sign-in.
Google Cast: Resolved an issue where the device left its assigned room after reboot.
Spotify: Fixed a bug where Spotify Presets required two triggers to start playback.

It's important to note that the device's firmware version is distinct from the WiiM Home App version. To check your device's firmware version, open the WiiM Home App, go to the 'Device' tab, tap the 'gear icon (Cog Wheel)' for device settings, select 'Device Info', and then view 'Firmware Version'.
