Does NANO "request form" even work? "'re-captcha failed", and no response for a while

At , if I submit a message, - sometimes I see "recaptcha failed", (but I don't see any), sometimes it write "your message has been sent", but I don't see any response for a while...
I am not sure if my messages ( yesterday) has been sent at all ,:frowning: , - please tell me if I am wrong?
Can you please add "automatically reply message", such as " we receive your message successfully, thank you for staying with Nano" which is sent to e-mail?

I just responded to your email, so it appears everything went through. Depending on timing, it can take a few business days for us to respond in some cases. We will look into auto respond setups.
