You can choose what to prioritize with a script such as [Userscript] WaniKani Lesson Filter if you want. You can’t “lose” a lesson or anything like that, but if you’re not careful with scripts like this you could get a really large backlog of vocab lessons. You want to avoid that by always doing 2-3 times as many vocab lessons as radical/kanji lessons. Personally I really preferred learning kanji and vocab together, so I did roughly 3 kanji and 9 vocab every day when I could. (I just did all the radicals right after leveling up.)
