I just got told this from Brent at samsung support
Unfortunately, yes sir in order for you to use the server correctly based off your region. You will need to switch over to the AU server. I do apologize for the inconvenience that this is causing you.
If this means manually switch over … (I’ve asked for confirmation of this) it will take me days and days. I’m not kidding. I have such a large setup on smartthings i simply don’t have the time. This is really disappointing.
EDIT: Yep confirmed
Unfortunately, we will be unable to assist you with that. Please contact our technical support department for assistance by calling Samsung Accounts: 855-795-0509, option 2. And an agent will be happy to assist you with migrating your account to a AU server.
