We have a sandbox sheet duplicated from a live sheet for 6 months now.
The automations on the sandbox sheet are 'inactive' as we don't want any alerts being sent out while we run testing.
However, just recently, email alerts have been sent from the sandbox sheet to the contacts and we know this for sure because the link in the email go to our Sandbox sheet. HOW IS THIS HAPPENING AND HOW DO WE STOP IT?
