Auto Notification not being sent

I have tried Applying a monthly count, and changing a monthly count, and in neither case did I receive an Auto Notification, but I am receiving other auto notifications for the same store, so I know that things are working elsewhere.

Reproduction steps:

• Store 01580
• Auto Notification Setup:
• 
• Store Contact:
• 
• MxC Notification Setup
• 
• Example emails that are being received:
• 

Test one - Change Applied:

• Find Applied Monthly Count
• Change Count
• Apply Changes
• No A/N received

Test Two - Apply Monthly

• Monthly Count (May 2019)
• Enter details
• Apply Count
• No A/N received
