Line 172 in 94f43bc

//languages: utilsInitializer.userLanguagesUtils().getUserLanguages(user_id),

Related line is commented out. (?)

Languages can be taken with get_languages call, however sending at login is better in terms of performance.

Commented line is in wake call, languages are sent in login as expected. Issue is invalid.
