I have set Bing as the default search engine in Edge Canary version 188.8.131.52 And, within Bing's settings, I have set the Country/Region to "India" and Edge is set to show in "English (India)" in Language settings.
But, whenever I use the search bar in New Tab page (The one which always says "Search the web") to search anything, it resets Bing's region to "United States - English". I would then have to go to Bing's settings to manually change the Country/Region to "India" back again.
This bug, however, doesn't occur when I search directly from the address bar.
But, as soon as even the cursor hits that search bar in New Tab page, it immediately resets Bing's region to "United States - English" even if I haven't searched anything yet.
