Redeem code broken in iTunes 12.7?

I'm trying to redeem a code for movie in the latest iTunes (12.7) in macOS Sierra (doing Account -> Redeem), but the redeem page doesn't have any redeem button, just a text box where I can type the code but there is no way to submit it. Also, the "Use Camera" button doesn't seem to do anything. Anyone else running into this?

Thanks,
