We need support for the Arabic language
While I don’t think that mondaydotcom (MDC) supports Arabic at the moment, you can add support for in your apps by internationalising apps based on your browser’s navigator.language property – assuming you are an app developer 
We don’t yet support Arabic in our apps, but we do have a subset of the languages MDC supports.
We perform internationalisation on the client side using user.currentLanguage from the MDC context (rather than using the browser’s navigator.language property). That way, when the user changes their language in MDC, we display the same language (if we’ve done the translations for that language).
