dynamic checkout buttons throw a JS error 50% of the time

Hi folks,

It seems that the dynamic checkout buttons on our product templates load inconsistently. About half of the time I can see a cryptic error in the javascript console that seems to be part of the button code.

51a14fb7a3aaaed66b48.322.en.js:1 Uncaught (in promise) TypeError: pt.HG is not a constructor
at Module.gt (51a14fb7a3aaaed66b48.322.en.js:1)

at Generator._invoke (spb.en.js:10)
at Generator.next (spb.en.js:10)
at f (spb.en.js:1)
at o (spb.en.js:1)

After one or two page reloads, the error disappears and the buttons work. Any idea what might be provoking this?

Did you ever resolve this? I'm running into exactly the same problem.
