Not Receiving Form Opt-In Notifications

Hi, recently, a number of my form opt-ins were captured and added to Infusionsoft, but I did not receive a notification of these submits. In the last 5 years of using Infusionsoft, as per programmed through Campaign Builder, I always receive notification emails, but in the last 7 days, I’ve a few submissions that were missed the email notifications being sent to me. I had to go to Recent Activities to see them.

I’d like to file this as a known issue but there was no such feature. Can anyone help please?
