Emails not being sent when order placed

Email notifications that I received an “order” stopped arriving a week ago. I don’t see where settings have been changed or wrong.
It has been a busy week and it is not unusual to have no activity for a few days. But I had an uneasy feeling and logged onto wix and we have 7 orders going back 7 days that notifications were not sent out.
Is there a setting or update that has changed? Is there something I can reset? Is there something I can do to test?

Completely at a loss

AFAIK, if you head to Automations, you’ll be able to see the automation that runs when an order is placed.

When you find the Automation, you can review it’s Run Log to see if it completed all the steps or if it got stuck anywhere - Wix Automations: Understanding Run Logs | Help Center | Wix.com

I’d also recommend reviewing your inbox and making sure it didn’t head to spam for example.
