How often are translations between crowdin and github are synced?

Just like in the title. Does every release have the newest version of translation files?

Welcome! Typically only for every major release (so for 57, 58, …; but not for 58.1, 58.2). For beta releases typically for every version (e.g. 59-beta1, 59-beta2, …).

I just saw you contributed to the Esperanto translation, thanks for that! Out of curiosity I tried to find this language in Android settings on my device and it’s not available.

Do you know or have a device where Esperanto can even be used as the system language?
