Not Receiving New Submission Email to Admin

I’m reaching out regarding an issue I’ve encountered with the registration form on our website. Previously, I used to receive New Submission Email Notifications to the Admin without any problems. However, recently, I’ve noticed that I’m no longer receiving these notifications.

I’ve conducted a test by sending a test email, and it seems to be working fine. Despite this, I’m still not receiving the notifications for new form submissions.

Could you please assist me in resolving this matter?
