I don’t have any definite answers, but I do have some ideas that you can try…
At the top of the main page of the Stringify app there is a symbol to click on to view the activity log. If any of the flows did run you will see them in there, and they will show that they sent the emails. If that is the case, then check your junk mail.
There is something strange going on with the date time Thing, sometimes you have to set the starting date back a few days to get a test to run today. And even once it does start working, if you go back to that date time Thing, you might find the starting date has changed to yesterday’s date. But once it’s working, don’t worry if you see that date change. Just be sure the first time you set it up you have the starting date back a few days.
I just did some testing using a button in the app for a trigger, and had it send me an email when I press the button, only if it’s nighttime. It worked once or twice, then didn’t run anymore. I didn’t need to check my email, I just checked the activity log in the app. Then I changed it to send a notification. That worked every time. And when I put in an email and a notification, after a couple button presses, I still got a pop up notification, but no email. And the activity log showed that it sent the notification but not the email. If I waited a few minutes, the email worked again. I suspect there is a limit on how many emails you send per minute or something like that. So you might not get all of the emails you expect if several of them happen around the same time.
So start by checking the activity log to see if the flows are running. Then move your starting dates back a few days and try again. But don’t expect to get a whole lot of emails at once, there seems to be some limit on that. And if nothing seems to be working, try making it send you a notification just to be sure the flow will run. If you still can’t get it to send you any emails at all, you can submit a support ticket with Stringify HERE.
They will be able to see exactly what is happening and help you out.
