Help!
I created a spreadsheet that is useful in my line of work. I created a second user so my co-workers can also use the spreadsheet under the second user.
As the owner of the original work, I set up e-mail notifications to notify me any time a change was made to the spreadsheet.
Since May, the notifications have been streaming in faithfully.
Starting this past Tuesday, no notices have been e-mailed to me.
I've checked the settings, all seemed ok.
I deleted all notifications and un-shared the spreadsheet.
I then shared it again and set the notifications for any changes, which it had been all along.
Today, again, still no e-mails, even though the spreadsheet is used periodically throughout the day.

any Ideas??

I am having the exact same problem.

did your problem start this week??
