This is kinda annoying. I have been using a virtual machine to access EhonNavi because I don’t want to poison my main system with Adobe Flash Player. However, upon upgrading from Ubuntu 18.10 to 19.04, I can’t get Adobe Flash to work any more. Neither on Chrome nor on Vivaldi.
To read the EhonNavi books I can still use the old VM (18.10) but I actually want to retire it soon.
I’m having the same problem. I came real close to saying eff it and installing flash on my main machine but I just can’t bring myself to do it. Please update and share if you find another solution.
I do have a (hopefully temporary) solution but this might not work for you. My work computer (Windows 10) has Flash Player so I’ve been reading the books at work 
This way I can still refuse to install Flash on my private computer but continue reading the books.
That would almost work except my work computer get remote’d into by my boss about 4-5 times a day lol
Will this be kicking off with Age 2 tomorrow? I’ve got to admit work has got crazy for me, so I’ve still got 5 books to go, which is terrible. But I’d like to keep going forward!
Hii! So unfortunately I don’t have time at the moment to do the challenges myself, so if someone wants to continue them, by all means :D. I have updated the web app to have all challenges unlocked. Also, Age 0 and 1 books have been updated. Ehon Navi added a couple, I think, so might check those out too.
If you run into any issues with the app, let me know. Otherwise happy reading 
!
