Since the original canary build released 8/4/2019, Microsoft Edge Insider doesn't support changing of the core language, if i wanted to say i want to change the language from English to French or Greek for example, it is grayed out. It is really annoying.
Hi @Deleted. We are working on getting the next version of the Microsoft Edge browser localized into many languages, but it will take some time. Please be patient with us. Thank you for taking the time to offer us this feedback, and for trying out our new browser. Please keep updating and letting us know what you think of our progress.
It worked for me like this: - Go to edge://flags/ - Search for "language" without quotes - Find "language localization" - Change from "default" to "enable". - Restart your browser - Go to edge://settings/languages - Click on "Add languages". - Choose your language - Click on the "3 points (more options)" - Check the box "View Microsoft Edge in this language".
