Hi krileon.
I installed CB Google Translate on my site, but I encountered a problem: Google Translate is visible in the desktop menu of the site but not in the mobile one.
I ran some tests and noticed that CB Google Translate doesn't appear in two CB Logins at the same time.
For example, if I have a CB login in the menu and one in the right div of the site, CB Google Translate only appears in the CB Login located in the menu.
However, if I deactivate the CB login located in the menu, CB Google Translate appears in the CB Login located in the right div.
I assume this is the reason why CB Google Translate does not appear in the mobile menu, as it is considered a "different thing".
I specify that the menu I use is "Maximenu CK", with its mobile version "Mobile Menu CK".
You can see an example

(click on the figure of the little man to the right of the menu).
