I paid some extra money to get the Dojo function for my Japanese course. But it seems to be disfunctional.
If I want to start the Dojo, it requests for e.g. 6 additional words to learn. After having learned those, it requests for another e.g. 10 additional word to learn and so on. Until know I was never allowed to start the Dojo. This is really annoying in particular there has been some similar complaints in 2018! So, please ask your software team to get this bug fixed (IOS 12.3).
