@MadhaviSeelam This might be invalid. I think country or region is set during installation so changing region post installation won't stick.

This issue is not valid anymore because we deleted hardcoded allowed country list.
Promotion will be shown with --enable-features=BraveSearchOmniboxBanner cmd switch always.
Instead, we'll control allowed coutry list via griffin.
