Using Dynamic values in the Reply To field in Sprout Forms Notifications I'm looking to have a Dynamic 'Reply To' for a notification when an entry is saved from a form submissions.

I'm using the below which is what the field is named in my form, but it seems it's not allowed? 

{email}
Ran into the same issue, asked the support team, and they confirmed it's a bug. 

Workaround is to comment out this line:
https://github.com/barrelstrength/craft-sprout-base/blob/v2/src/app/email/elements/NotificationEmail.php#L481

Tried it and it works fine. 

They said it would be fixed in an upcoming release.
