Bug? verifyBuyer() never calls its associated callback on IE11

Hi!

I noticed that on IE11 browser I never get a callback to the registered handler from verifyBuyer(). The checkout process therefore just stalls and I have to bypass Strong Customer Authentication for the payment to succeed. This affects only Internet Explorer as far as I can tell. Firefox, Chrome, Edge, Safari are all fine. isSupportedBrowser() returns true for IE11, so I guess, it is supposed to be supported despite its age… :slight_smile:

Thanks,
Frank
