I’m regularly using wanikani on my phone, in the web browser (firefox/fennec).
I’ve recently switched phone, and now when typing something some kanas repeat themselves, e.g., しゅうでん becomes しゅしゅうでん.
If I type slowly it does not happen.
If I use the Gboard keyboard it does not happen (but it happens with all the alternative keyboards I tried: AnySoftKeyboard, Hacker’s keyboard, OpenBoard).
This problem was already discussed in these old topics:
I could use a third app (people mention Flaming Durtles works fine), the Gboard keyboard, or type directly the kanas.
However, my question is how to debug/fix this problem for alternative keyboards? Is it something that should be fixed on wanikani side, or is it something that should be fixed on the alternative keyboards side?
