Lol, you know how it goes. I got side tracked with a million other things that are smart home related and actually made so much progress, the fridge is one of the few outstanding issues. I have not tried again to make the connection but ill try right now.
*Edit I have successfully made the connection and I realized why it failed the first time (that external Samsung load page takes a long time to load and I think I was impatient with it the first time).
I can see the fridge and the tv (the only two devices still on my samsung hub). I know the fridge says unavailable but I will play with it and test your use case/issue above.
