How do I download or get the New Admin Template. I don't see anything new. Thanks

Click "New Design" [CRTL]+[N]

here you see the templates...

choose Bootstrap 4

there you can see the "SB Admin" Template click and create

Hi Thank you for your help But that did not look new to me. I'm sure I have seen it as an option there before. Thank you
