I've seen the prior posts in regards to the same issue. I did a factory reset & I can't add my Google Calendar to my Smart Hub. My account is also the primary Samsung account. I get a "Server error: 500", when i attempt via my phone. Please help!!
I am having the same problem. When I try to sign into my Google account on the refrigerator it just spins endlessly. Trying it through the app results in the server error. Never had a problem before.
