Samsung Washer and Dryer

I registered my Samsung Washer and Dryer with my Samsung account, and I can use them both via Smartthings app. However, when my wife tries to use them in her SmartThings app they both prompt her to register them and she cannot use them. She can see them in the location “Home” and in the correct room “Laundry Room” as I configured them. I have updated both our apps and restarted our devices.
Any ideas?

I have a Samsung washer and dryer and usually the app does not let do anything. But I do get notifications when the cycles complete. Pretty much all I want from it.
