I have budget summary with Alerts set to send out emails to people shred to the sheet if certain criteria happen.
So far, I am the only person receiving notification.
I have tried:
Send to specific people
Send to everyone shared to this sheet
as those are the only two options that pertain to this sheet.
Again, as the Owner of this sheet, am the only person receiving notifications. None of the other three (3) people have received ANY notifications for this sheet.
We have other sheets that notify these same users for different criterium that are working fine.
