Samsung S90C
From Rest of What I Know
Trouble Staying Logged In[edit]
Samsung TVs have a problem with email addresses that have a `+` sign in them. If you do that with your Samsung account then you won't be able to stay logged into your streaming service logins since your Samsung account is how your TV stores the login state (I know, crazy).
This also makes Airplay unusable for things like streaming Youtube since the way to use accounts is to keep hitting the button over and over again until it suddenly logs in. Switching the email to one without a `+` sign will fix it entirely
