Forms Version 11.0.2307.40547

I've had several users complain about their forms timing out before they can submit them.

They claim they are not getting the message about the form failing to submit with the button to reload the form - but I think they are just ignoring that page - because I definitely get that page consistently when I sit on a form too long.

In any case, I'd like to look into extending the time period that they have to submit the form before this timeout happens.  I'm just not certain where to find that.

I'm not using the Session Timeout setting, so it's not that.

And I'm not finding anything that sounds like the right thing under the new "Advanced Options" page in the Forms Configuration.

Does anyone have experience with this setting and where it can be modified?

Thank you!
