'to' name/email in notification email not visible

In the past, when I received my notification email, the 'to' area included the other people who also received the notification email.

Today, I was only able to see my email in that area, not everyone's.

Is this a change in JotForm function, or does this signify that the other person's email notification did not go through?

There have been no changes in the notification emails in my jotform. In the past, this same form included all the emails listed in my notification email.

In order for us to be able to check and reproduce the issue you above discribed, as I have tested the email submission and autoresponder with a test form, however was not able to reproduce it.

Please take a look at the following figure:

Thanks.
