Not being able to purchase a lesson – Learn Japanese! - Kanji Review

Hello, for some reason i can't purchase a lesson in this app, just because your website is down i've decided to reach out to you in here. Could you please somehow contact me somewhere? I would like to buy a lesson and pay for it with paypal or something. (paypal didn't work either from the app)
