When an FAQ article is created and/or updated, the ‘updated by’ and ‘updated date’ stamps are displayed in the FAQ Dashboard in the bottom right corner next to the FAQ article that was updated, e.g. “69d by Renee”.
However, this information applies only to the languages selected when that FAQ was updated. If an FAQ article is updated only for a particular language (such as Russian) then the last ‘updated by’ and last ‘updated date’ will only be visible for the Russian language, and not for any other language FAQ.
Additionally, if 3 different people modify the same FAQ for 3 different languages, then the corresponding date and time will be visible for the respective language.
