Sorry to hear about this concern persisting, neighbors. When it comes to video connection, it is important to consider wifi and mobile connection variables. Narrowing this down can be quick and easy with just a few steps. Give our Rapid Ring app a try, if you are not already using it, as it is designed for the quickest access to live view, which is most important when not you are subscribed to a Protect Plan subscription. Please also ensure there is not a vpn enabled. As it looks like most of you have covered the network troubleshooting steps, your device health RSSI should be sufficient as reflected in this Community post.
In addition to the above, and as I’m seeing many neighbors mention motion event concerns, try disabling Advanced Motion Detection settings such People Only Mode, or even setting all your settings to default. If live view works with the most default settings, feel free to enable your desired settings and ensure the Ring app is performing as intended with each, on your mobile device. Pease let us know if this helps.
