I've seen a couple of threads describing the same problem, but none of then provided a valid solution for me. The Nest Mini is unlinking everyday from my Google account.
The Nest Mini is correctly connected in the Google Home App through the 2.4gz Wi-Fi.
I already tried rebooting and also factory reset, it keeps the same.
Firmware version: 277099
Cast Firmware version: 1.54.277099
