Cannot select other that my default language.

NO WORDS IN IT, It's like it's from the 1800s or something. VERY few modern tech-based words make it in here. You got some great woke terms didn't want to miss out on that. BUT "NATIVELY" fuch that, that's not in there. How about a very common name like REBECCA? NOPE why would that be in there? I have literally added over 1,000 words manually to this dictionary that's how disgustingly lacking it is. You guys should be embarrassed with yourselves. Been complaining about it over three years and filed at least a few hundred bug reports, and nothing. NO fix, no side-loading (dot)DIC word banks to fix your incompetence. Same old terrible dictionary. FIX IT ALREADY.

is ok
