Support was very helpful

I had an issue on a site where this plugin is installed which caused the “Reply To” field to go missing. The plugin was previously working just fine for many months and the “Reply To” field was always there, but after an update, it disappeared for some reason.

I contacted support and they replied that they knew about the issue and that it was fixed in the beta update they had just released, and gave me a link for that. I installed the beta and it fixed the issue. The next day, the main version of the plugin was updated to include the fixes in the beta release.

Thanks for your help in solving the issue!
