I believe there should be an option to disable this on Android because it sometimes tags words incorrectly.

See, I am learning Korean and today I came across the word 사고 which meant "accident" in the context I encountered it in. However the app incorrectly tagged the word as a verb 사다, which means "to buy".

I was able to remove the incorrect tags in the web version, but they are still present on Android because the option does not exist (yet).

By the way, an option to edit and delete tags on mobile wouldn't go amiss either.
