Pay $9.99 per month button doesn't work - Ad-free Duolingo
Windows 10 (build 15063), Chrome browser (61.0.3163.100 64-bit). Entered credit card info but the payment button never activates (it doesn't becomes bright blue as, I suspect, it is supposed to). I'd like to give DL some revenue, but the company needs a working payment gateway.
Seeing posts like this sums up what I hate about DuoLingo.
It's such a beautiful, amazing service, and they shoot themselves in the foot. It really makes me question the competence of the people who develop and maintain the site.
