2 Step Verification Issue

Since updating to Sierra, unable to verify 2 step verification with the Twitter App. I am propted, but all tha tappears is a solid wide square screen where I should imput data. Nothing populates. Una le to verificy.

Called AppleCare. The brilliant mind at Apple suggested I disable the fearture at Twitter, log in to the app and then re-emable 2 step verification. Voila, it works. Please Twitter, fix this issue.

Thank you Apple!
