The app doesn't allow to enter a booster vaccination, 3rd vaccination from overseas, in my case Australia. Also, when entering the date of birth, you have to scroll back in time month by month until you get to, in my cas 1953! Took me about 3 years of scrolling and in the end the app didn't recognize my vaccination. Really frustrating. If they want to have more tourists in Indonesia, Bali. Get your act together. It's absolutely appalling. This is written before the entry to Bali. March 2022
