Dropbox

Hi
I have problem finding my Dropbox account When I work on my computer and put all my files in to drop box and it works great. When I got a new Galaxy 8 note I can not get drop box to sync Did all the prompts phone in front t of screen ect. What I realized is I have two drop box accounts one free attached to my gmail and one I pay for ( least expensive business account.) When I go to drop box on line it will only let me see the basic account I tried every way I can think to change over to my business account and it will not let me. Tried
calling Dropbox but that is useless So with out going to business account on line I am only able to sync with the basic account which does not have my work files in it.

Any help would be appreciated
