I can confirm this issue. My VDB v2 keeps showing as offline. When the button gets pressed by my neighbor, the mechanical doorbell will still ring, but everything else is inconsistent. Sometimes my other automations will run delayed but sometimes not at all. One time my automations (flashing color bulbs, and Alexa announcements) happened MINUTES late.
I can’t stream it or anything though. The device says it’s offline, and then will randomly come back online then randomly go offline again for some time. It’s inconsistent. It self-heals and then repeats.
I posted this issue for the Fix-it-Friday event, but I probably posted too late. Hopefully it gets addressed anyway.
