Access and Expirationdates

Hi, some questions I hope you can answer, according to WB access to a submission:

  1. What is happening in a technical manner, when a WB logins into a submission and reads the submission, before the “Expiration date for access”? What is activated or registered?

  2. How many days will a WB access be extended to, when a WB logins into a submission right before “Expiration date for access”? And will there be a new extension everytime the WB logs in?

  3. Does WB and Recipients access follow each other, when the WB has logged in to a submission before the submissions expiration date? Fx. when a recipient extends the submissions expiration date, will the WB access to the submission also be extended?
