Problems with Paypal option with BrainTree

So I'm trying braintree out for the first time in years, the "pay with card" option works as expected but when I go to the paypal option the modal pops, closes, and errors out.
parent.js:168 A boolean is being passed as a fourth parameter to window.open. This is not used and may cause an exception in a future release.
window.open @ parent.js:168

I'm certain that I'm forgetting something obvious, and was hoping one of you could point out where I'm goofing
