@Rgarrets1977 Lets have you try testing Live View on cell data only, with WiFi off. Can you please tell us what happens? If Live View doesn’t pull up, can you please try connecting the Pro to a hotspot? This will help us narrow down if it is the network or the device.
1.Toggle on a mobile hotspot on a secondary phone
2.Change the hotspot password to 12345678
3.Confirm hotspot is on and broadcasting
4.Literally set that phone down near the Ring Device
5.On a different phone/tablet, proceed through the setup, connect the Ring to hotspot
6. Once connected, allow the Ring to update completely then test an event
Settings>Connections>Mobile Tethering & Hotspot>ON
Please note, you mentioned all your devices work inside, however, is this the only device outside? Brick, stucco and stone can cause WiFi interference.
