Hi Suzanne

I also experienced an issue on reminders yesterday where a notice was received form QB to say they had not been delivered. However they were delivered to my g mail e mail that I have had to set up to receive copies of the invoices so I assumed customers were receiving theirs and we do get some payments almost straight away so assume that they may be working for at least some customers.

This has randomly occurred before 

I have not bothered reporting as its a waste of time. 

Let me know if you have any further info on this. Thanks C
