I am on version 4. Trying to use SquareUp and getting this error on the checkout page (when looking at the console): Content Security Policy: The page’s settings blocked the loading of a resource at blob:https://connect.squareup.com/<removed a code> (“script-src 'unsafe-inline' https://js.squareup.com”).
This is causing the page to give the following error when I try to checkout: Failed to get the card nonce
I have removed the SquareUp option, I can reproduce it locally as well. No meta tag on the site and I don't see it being setup in code either.
I think it has to do with an iFrame inserted by the plugin.
With that being said, I am moving to BrainTree right now. Verified it works in dev, just waiting for a merchant account to be created. I'd rather use SquareUp, but I need something that works.
I'd like to know if anybody has SquareUp working on 4.0.
