Re: Configure time out for post adaptive card and wait for response and move to next step
Hey,
you can set the Post adaptive card and wait for a response action to have a Timeout.
To do that, click on the 3 dots and then on Settings.

In the Settings, you then enter PT15M, to have the action time out after 15 Minutes.

Now, below that action, Add a parallel branch.

On the left side, you click on the 3 dots and under Configure run after, you select is successful.
On the right side, you click on the 3 dots and under Configure run after you select has timed out.

Now if someone answers the card in under 15 Minutes, the left side will trigger and you can continue your logic there.
If the adaptive card times out, you can continue your logic on the right side.
If you want to have the same actions happening after one of both actions have completed, continue in the middle below them. But make sure that the next action below has the Configure run after set to is successful, is skipped and has timed out.

hope this helps. I think you'll have to play around with the Configure run after settings to get it the way you want...
cheers
