Mautic Campaign Reply Decision Branch Not working as expected

Your software
My Mautic version is: 4.4.4
My PHP version is: 7.4
My Database type and version is: MariaDB MYSQL

Your problem
My problem is: In Mautic campaign Email Reply Tracking is not working as expected. In campaign (see picture bellow) I have separate branch (decision branch - Green) which should be activated only when user replies, but the problem is that that branch is activated no matter what, it is activated in both cases, when user replies and even when user does not reply.

The final goal is to stop sending follow ups after user replies. So under Right green branch (see picture) first user is added to replies segment and then marked as “do not contact”

Here is campaign

Hello,

Did you set up reply detection and tested it?
(Give Mautic access to the email address in question where replies are coming in:
Contact replies | Mautic)

Thanks,
Joey

Hello, @joeyk
Yes, all Mautic configurations in Email Settings are correct and showing success (green).
I only have 1 mailbox where we are sending from and where we are aggregating replies and that mailbox is added in mautic email settings.

In mautic configurations: under “Monitored Inbox Settings”
all of the following are set up with custom connection settings and showing success:

Default Mailbox

Bounces

Unsubscribe Requests

Contact Replies

There was a bug, that a reply was not detected by Mautic, if it was not first read.

Do you have the pixel inside your emails?

Can you try first assure that an email is marked as read inside Mautic and then reply?
