Thanks for your patience. Could you tell me which page you are having issues trying to edit? I've edited the translated page here hidden link and it works fine as shown in the attached screenshot.
Thanks for your reply. It seems to work fine when I tested it as shown in this screen recording hidden link . Are you the administrator or just an editor?
Thanks for your patience. I've added "Editor Test" as the translator and assigned the Chinese language. Now the editor can edit the translations as shown in the attached screenshot.
