After I turn ipv6 on everything runs fine for a day or two, and then my network shows as offline on the Google Home app and I'm unable to change any settings as my connection seems severed.
Internet and the local network still works fine, except for ipv6.
Only solution I found for now is to factory reset and keep ipv6 off.

Yes, I still have the issue.
Extra steps I took were testing ipv6 cabling a computer directly in the ISP modem, and it works normally.
And I found that the issue is solved temporarily by power cycling both ISP device and the Google Nest, which makes troubleshooting a little easier, as I don't need to factory reset anymore. The problem comes back later, though.
As an update for you, I wanted to let you know that we have a firmware update coming out now. Some people may have already received the update, but most will see it coming still. Everyone will have it before the end of April. If you receive that update and don't see an improvement in your issues here, please let me know and we can keep looking into things.
Just as a bit of added info, the update version for both Google WiFi and Nest WiFi will be 14150.43.80. If you are seeing a different version number when you check in Google Home, you have yet to receive the updated firmware. Let me know if you have any questions about that.
I'm just checking in to see if you saw my recent updates and to see if you were still looking for support on this. Let me know if you have any questions and if you're still following things here.
