tab s7+ wont unlock

[Tanyaooo]

Just got my new galaxy tab 7+ and charged over night, requires pin to open and unlock (no biometrics avaliable) but it won't accept my pin. Have tried restarting (on and volume down button) but that didn't work. Not impressed since its only been released today!! 

Please help otherwise I will return it.

What sort of pin does it require?

[Tanyaooo]

My passcode which I had used all day but now it won't accept it.

@Hayley1963: Try signing in to Find My Mobile via an internet browser using the Samsung account details you have registered to the Tab S7, and you may be able to remotely unlock the device from here, depending on your security settings.
