Oh I see, sorry - I misunderstood. In that case, no! I’m not very good with different fonts in WaniKani, but funnily enough I’ve never found myself missing a kanji while reading and thinking it was specifically because of the font.
I wouldn’t use Jitai in a way where you feel like you’re “re-learning” the kanji. Personally I just see it as a way to gain exposure broadly to the different ways things can be written. I try to do my reviews without rolling over the cursor to check, but if I don’t recognise it I’ll look at the default font before answering.
