Automated mail merge and emails not working intermittently
I am using your add-on to facilitate groups registering for an event. I have your add-on merge their info from a Google Sheet (that is generated by their responses to a Google Form), which then emails them an invoice for payment. It has not worked on two particular days: January 23, 2020 and February 6, 2020. Both of these days, the documents did not produce, and since there was no document, no email went out. Why is it failing from time to time?
