The default time-out in PPO is 60 minutes.
A session would time out if you haven't had a page request within 60 minutes, such as navigating to a page or hitting the Submit button.
Capturing data is usually quick and easy, but we sometimes get sidetracked by something else and forget to Submit.
PPO has you covered for this!
In these circumstances as mentioned above, if your page is still open and you get timed out, PPO will remember the data you have captured. When hitting Submit, and timing out, PPO will take you back to the Add / Edit page where you can Submit the data. It is important to note that PPO will only remember data captured for the last 24 hours and this only works when on a single Add / Edit page.
Below is a short video demonstrating the above.
