I was able to run this flow a few weeks ago without any issues. There was one difference during testing. I was sending all the emails to myself (at two email addresses) - instead of my member list. I was able to send out 20+ emails (at one time), but when I tried this last week with email addresses for my members ... it just stalled, like I described.
This was a crucial step in my work, so my only workaround was to do one email at a time. I would do as single trigger on one line in my sharepoint file and have one email sent. If I did more than 5 triggers / emails, it would hang but might eventually complete all 5 after 45 minutes - or not at all. In this instance I only had 67 emails, but I will have >200 to do shortly, so I will need to look for other products / solutions.
Yes, I reviewed the troubleshoot list, but like I said, I didn't receive any failure notifications - not sure what to look at in more detail.
