I have been an avid WK user, doing my tests on my android phone’s WaniKani app. Well yesterday, the app blew up. So I decided to reinstall it (for the first time since 2018). When going to reinstall it, the option was replaced with Flaming Durtles and a different logo.
I popped in my API and was able to get it to run. There are a lot of benefits to this new app, however, I find that when I make hasty typos, there is no way to undo a submitted mistake (whereas the old app allowed you to backspace to alert WK that it was a typo, rather than failure to remember).
