FormidablePRO – Reply to issue

Hi,

I use https://wordpress.org/plugins/formidable/ for contact form.
The only issue is: “Reply to” not working.
I’ve set in FormidablePRO reply to address “jon.doe@example.com but is ignored.

I read here that the same problems are with Contact form 7 and Gravity forms too:

I migrate from Mandrill to SparkPost and I want “Reply to” work correctly, in business Reply to is a must!

Any chance to be resolved?
