So after triple checking, im not sure why wanikani doesnt accept this response. Its supposed to be a reading, and it matches but it says its wrong.
The reading is “jou”, but you’re entering “jiyou”. じょう vs じよう.
Alright thank you, thats going to be the hardest part i bet, remembering that
While the person above essentially answered the question, the knowledge base thing also has a section about it(and answers to other common questions) if there are other related things you don’t know: Small vs Big Characters | WaniKani Knowledge
WK pleeease add a low-level “hey it looks like you typed a large よ why not check out this article …” pop up for new members in reviews. 
Don’t they tell you you should know hiragana before starting to use WaniKani?
They do.
But chalk it up to human nature I suppose. I don’t think people are jumping into WK without having studied hiragana, but I can easily see how some people could get excited to move forward and totally miss stuff like the small ょ. And obviously that’s not a fault of WK but if we know it’s going to happen and we can catch it at the right time why not … that many people less likely to get frustrated early on.
Not all kana sources mention the combinations, or mention them correctly.
+1 for linking to that article on known problem level 1 items. @CyrusS
This problem had me well even though I knew about small characters. I was typing it wrong all the time until my friend mentioned it
