Thanks for reaching out.
Sorry to hear about your experience with your Google Nest Hub Max. Let's see what's causing this to happen by answering these questions:
Let me know how it goes.
Nothing else is experiencing this as far as I know.. it just randomly occurs.
it's like 10 metres away from my wireless access point (I'm assuming that's what you're looking for since it's a wireless device and not plugged into my router)
Rebooting it has had no change in it happening.. still happens randomly.
Thanks for the details you've shared.
Let's go ahead and perform a complete reset to see if this would change its behavior. I would suggest that once you set that up, make it closer to the router preferably within 10-15 feet until it completes its set up.
Keep me posted.
