You can still Pin by copying a link (ctrl c), click the Add+ button at the top of your page, and then paste the link (ctrl v). A little more work, but you can still get your Pins pinned!
my pin button works, but I just noticed it's not recognizing the text that I enter for the description. once I pin something, I have to go over to pinterest, click on the pin & edit and recopy the text. but then it's fine.
