Locale Switcher doesn't work in myvtex environment without explicitly setting the workspace/environment, but there is no impact on the website. This behavior impacts the navigation only in myvtex and content management for different languages.

• Access the Site Editor or the Front-End in the myvtex environment without putting the workspace (e.g: accountName.myvtex.com/admin/cms/site-editor);
• Select a website with multi-language;
• Change between the languages;
• You will see there will be no change in the language.

User "master" workspace to change content for the different languages and validate it while navigating (e.g: master--accountName.myvtex.com/admin/cms/site-editor)
