Notifications not be delivered to all emails

We have recently started noticing that sometimes our JotForms are not being delivered to our email. We have troubleshooted this issue down to it being something wrong with the "Notification" now "notifier?" within JotForm. We had a form called "Vehicle Incident" and it had 3 seperate emails setup as notifications as it has been this way for 2-3 years. All of a sudden it was only delivered some to the 1st email address in the notification. I sent an email and it was not delivered to all. I deleted all the notifications, created a distribution list on our side and created that as a Notifier in JotForm and sent and everyone got it.

I noticed that it doesnt say "notification" anymore and says "notifier" leading me to believe possibly an update you have done caused this? Any help resolving this with our other form is appreciated.

here is an additional example that is having the same issue where they get some but not others. I did NOT correct this one so you could further troubleshoot:

Hi,

We had some issue recently with out main email system which is repaired by now, but has caused some issues to some of our clients and unfortunately you seem to be affected by that as well.

What I would recommend is next.

Set new notifications (from start). They can be the same, but it is important to set them up again.

This has helped others to get their submissions to their emails as before.

You might find these useful for that:

Do let us know if setting the new notifications worked for you.

Deleting the notifications that are not working and rebuilding does not resolve this issue. All are working except one and it has been rebuilt.

So far your email notification got only 1 email address in it, which is a******t@s****h.com

As explained by Ben, there was a problem recently, but it's been resolved, please add the other recipients, separated by a space, then a comma, making sure you do not put a comma only at the end.
