Roonready zone disappeared from list

I have been using roonready as my primary zone for my main system ((ethernet to micro rendu to schitt yaggdrasil)
The RoonReady option has disappeared from my zone list . Micro rend still power on and light blinking as usual without info(music) flowing to it.

Any thoughts?

Reboot the mR / reload its firmware with the current version. Reenable the mR in Settings>Audio
