I'm not sure this is my problem... I think that some way my account ended up in the Seller Hub.

 iI have tried to switch to my eBay selling .  click on the box that says ... switch tools... get the response.... couldn't switch you back... try again

You cannot "switch back", there is nothing to switch back to, it's gone.

To get used to Seller Hub I suggest you bookmark
