Ok I have got this flow sorted to some degree,
The recurrence and the sat/sun - 8-5 stuff came from this post https://www.alanps1.io/power-platform/so-you-just-want-flow-running-in-business-hours-8am-to-5pm/
And the rest of the flow is something I made to warn me if the support desk doesn't check the emails for support
But..
I'm wondering if I am maybe using it wrong?
1) If the recurrence is going to trigger every 15 mins this presumably cannot finish its check because of the email 30 min and 15 delays lower down. So it will get mired down in the rest of the flow?
2) Can I move the Get Email V3 to the top so it only trigger the checks on the event of a new email ( which seems more sensible)
3) Can I replace the Recurrence with the Get Email V3 ? Will the date and time part still work properly if i do?
4) Is it ok to start the Yes with the Delay?

Im hoping my working out makes sense and that it is possible
