Contact Form Reply-To Stopped Working Properly With Gmail

For some reason after many years working properly suddenly reply-to stopped working well with gmail. I checked and incoming message has correct reply-to customer address (sent via contact form). Althought when I click reply I get my own email adrress as a reply-to, instead of the customer address.

Someone have the same issue? Any idea what could be wrong?

Thanks. Probably I could not find it because the topic in this thread is not really correct since Gmail can send emails to the customers but ignores reply-to address received via contact form. Also looks like there is no solution for this so far.

Since few days ago gmail started to work properly again with reply-to address received via contact form. Looks like it was Google bug.
