Sorry if this has been asked before (I’m sure it has).
I already have patchy kanji knowledge and am using many of the words I knew during my reviews, which seem not to be listed. For example WaniKani didn’t have ‘skill’ for 技術 which is annoying and sets me back, so I add it in during the review (because annoyingly you can’t add synonyms during the lessons!).
Sometimes if I get it ‘wrong’, then add in a correct synonym, it will let me move up an SRS level. However sometimes, it accepts the new answer as correct, but because I got it wrong before it moves me down a level.
This whole time I have not been able to work out what’s going on and what the secret it, it seems to be chance that sometimes it will accept that I knew it, and others will take me down.
Help, it’s incredibly annoying to have a vocab demoted because I used a synonym not in the system!
