I opened my Classic SmartThings app this evening and was told we need to migrate your account. Not a problem, I already had a Samsung account with the same email address and had set it to the same password.
So when prompted to enter my Samsung email address, I entered it and then the password. I was informed that the password was incorrect. I reset the Samsung account password and continued the migration. After 2 minutes I was told the migration was complete and that I would be logged out of any other device and that I should continue to use the Classic app. At this point I was put back in to the Classic SmartThings account and everything was working as it should be.
I checked my other device to find it had been logged out. So I logged in, I now dont have the option to select a Samsung or Smarthings account, so I used my Samsung one with the changed password. Login was successful but there all of my devices and apps had disappeared.
Some of my automated events still worked so it was still working. After a bit of digging it looks like a duplicate location has been created with nothing in it. This looks to be the default location now when signing in to the classic app, when I select the other duplicate location all my devices and apps are back as normal and can be controlled in the app.
Can the empty duplicate location be deleted now?
Or will this break something when the migration to the new SmartThings app is complete?
