We have Customer Voice integration enabled for our Dynamics 365 Marketing. When I send marketing email with a survey button, the email is received without the button (neither if we open the email in web-browser or email client).
It doesn't matter if I send directly the email or if I use a customer journey to send it, the email is received without the button.
With the sending by a customer journey, the Survey is well added in email elements on our Journey.
The button appears when it's linked to an URL but not appears when it's linked to a survey.
Could you help to figure it out please?
