Hi Ella!
on facebook in the top menu you see the avatar for the account that you are currently managing facebook from
to switch click on the button/icon on the right hand corner--the triangle/down arrow. it will say "use facebook as" with a list of your pages.
Your etsy shop is linked to
https://www.facebook.com/JoyOterHKto change where your etsy shop links to go to Your Shop-->Settings-->Info and Appearances and change the page to your
www.facebook.com/JoyOterJewelry
if that doesn't work go to facebook and disconnect the etsy app.
the option is under the same link triangle/down arrow link on FB...just scroll down to settings then on the left side menu in settings look for the "Apps" link in apps you'll see the Etsy orange logo.
Once you disconnect there go back to etsy and try again to set link your shop to the page you want.
hope this helps!
Clarissa
