Hi, I opened a ticket with the support about this issue (#5635352). It would seem that the block option interferes somehow with the translations. Even if I didn't use blocks in my article, the option was enable and for some languages, it was impossible to save the translation. I got the error message "Translation wasn't updated". It happened also when you want to publish. Not happening all the time though, I created a new article this morning and enabled Content blocks and everything worked fine.
