Noticed this issue in the last day using the Duo SDK. Was working for months without problems before now.
Loads the prompt for your type of push, you click send me a push, and you click any of the options you have setup like Send Push, Call Me, or Enter a Passcode and the following box pops up.
By this point all the coding magic is happening inside the iframe, so I am not sure if this is something I can resolve on my end.
Thanks in advance.
