Google Nest Mini Removed from home overnight

[DonkeyDuck]

Seem to be having the same issue as many others, where i have 1 (out of 3) Google Mini's that keeps giving me a notification overnight that it has been removed from my google home setup,

Its not a wifi issue (its right next to my hub and doesn't disconnect at any other time)

Sometimes, it sits there in google home right at the bottom of the Devices tab (under Local devices but not in any home or room), and i can just add it back into the home,

Other times, it needs to be set up from scratch again,

So the fact it keeps the Wifi password and configuration but just gets removed from my home seems to suggest the device is ok and it's a server-side issue,

The other thing is that it keeps switching between 2 different names when it disappears and reappears in the Google Home app (without me carrying out any reboot, or disconnecting and reconnecting)
Sometimes it comes back as NestMini7480, sometimes it comes back as Speaker 1, (Speak 1 was the original name i gave it when i first set it up, but i haven't bothered calling it that when i set it up the 100's of times its disconnected since, i just leave it with whatever name pops up in the setup, which again randomly changes between the 2)
That leads me to believe that there's a duplicate config somewhere server side for the mini i have that's causing issues, but i'm not sure where to go about it.

System Firmware 348702
Cast Firmware 1.56.348702

I've also tried the Factory reset from the device (hold middle with mic off) several times.

Thanks,
