Hello @paco,
I can confirm Localization still feels like an early release but support team is working actively on it.
- After enabling localization, CMS Item status is not accurrate anymore (Everything is set to Staged for Published)
- CMS Collection Option (Dropdown) fields cant be localized
- Page links in rich text aren’t translated (i.e. secondary languages point to the primary locale)
- Dates can not be translated
Fixed by support team 
:
- Translated content is overridden by primary content and vice verca. Also confirmed here: Has anyone noticed regressions when doing localization? - #4 by Simon_De_Ridder
