Why I'm unable to get passed recaptcha on chatstep?

I am a mobile user of internet chatrooms. Until recently I was a chatstep member, then when they started working on beta. I could no longer get passed recaptcha, I keep trying and all I get is a pop-up saying unable to capture.

I'm sorry, but I'm not sure how this is related to our Forum? Could you please let us know what is the relation and how we can assist you?

We'll wait for your response.

Thank you!
