Thakn you for contacting us.
Unfortunatelly, we don't have options to show country flag in any of our widgets.
Instead, in our Awesome plan (15$/month), merchant can show reviewer Location in each review by turn on the setting here:
Settings > Review Widget > Widget Body > Shop and Reviewer Details
or click on this link: https://judge.me/settings?jump_to=shop+and+reviewer+details
Let us know if you have any questions.
Is there any way to show country flag instead of name in title?
