Issue with Plugin Blocking All Countries Instead of Just UK

I’ve encountered an issue with the plugin where it seems to be blocking all countries, not just the UK as intended. I’ve double-checked the settings, and everything appears to be configured correctly, but users from other countries are still being blocked.

Could you please assist me in resolving this issue? Is there something I might have missed in the setup, or could this be a bug?

Looking forward to your support. Thanks in advance!
