Why are definition reviews so slow to come?

I’ve been looking at my lists, and many words “definitions” remain white for a very long time after the other reviews are a deep green. What’s up with that? Is there a way to make definition reviews pop up more frequently?

Currently both iOS and the website apply additional spacing to related prompts. For example, if you study the writing for 亮 then it’ll push the definition, reading and tone out for that character as to not give you a similar prompt type too soon. Can you send me an example of a definition or two that you feel you should be seeing sooner?

One thing you could try if you already haven’t is only reviewing definition prompts for a bit. That might help force a few more notoriously absent definition prompts back into the spotlight.
