Another question:
The flag (language switcher) does not appear in Header Buider. I tried but not appear (at this moment temporary flag is at main navigation)
What am I doing wrong?
Yes, I see the process of the header translation and I see the problem, I have submitted to the development department and we will get back to you soon.
My question is how do you add the language switcher? You can assign the language switcher to a menu, and I see you have successfully added it. Please provide more details on this issue: #325770
