Thanks for the update on this, @Northcutt! It sounds like you are doing everything correctly here. As long as the Ring app works fine and you are able to get live view via the Ring app, this is a great sign that your Ring devices, mobile device, and Ring app are working normally.
If it seems like the video quality or loading concern is only during the Samsung integration, the best next step is to check wifi signal strength to the Samsung device in question. Please also ensure it is connected to your 2.4 Ghz wifi, rather than the 5 Ghz. As you mentioned it being a Samsung TV, we’ve seen neighbors previously share success in updating their TV or ensuring other TV based apps or features are not interfering with your video stream. I hope this helps!
