Hi @Roman L Thanks a lot for checking it. I have changed the setting in the Developer mod and it works. Thank you.

It would have been good to have all the configurations/settings in one place. We have some hCaptcha settings in Settings > Site Security and some in the Dev mod. That's why i didn't get it to work and there is no mention in Settings > Site Security to advise people to change the settings in the Dev mod as well.
