Then Delay This Action

In the native routine automation, if you have three actions in the Then section, each with a ten minute Delay This Action: Do the delays run all at once (after 10/minutes all three actions would’ve run) or One at a time in sequence (action 1, then ten minute delay, action 2, then ten minute delay, action 3 then 10 minute delay) takes 30/minutes to run the routine?

They are in parallel. If you want to run them sequentially, you have to simulate it by staggering the times.

Thanks. I was gettjg curious results and couldnt find anywhere it was explained clearly.
