One-sided kana is katakana. Might be easier to do the reading first on this one.
片 is かた, and 仮名 is かな. Put them together to get katakana.
平仮名は分かりますが、片仮名はまだ覚えきれていません。
I know Hiragana, but I’m still trying to memorize Katakana.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up whatever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
