At the moment, our token expiration is set to four hours. This means that regardless of your activity in Applaud, you will be signed out after four hours automatically.
This is something that we are working on and will update shortly.
While we are improving this, if you know that you want to spend a bit of time creating something in Applaud, you could sign out and back in again before starting the task.
We know that this is not ideal, but we are working on a solution. We apologize for any inconvenience caused.
