Paypal Sandbox - by: Achille

Hi, I'm trying to use the paypal payment plugin in Test Mode.
I have some questions to ask:
- As soon as the customer signs a new subscription with PayPal subscription it is loaded as "Pending";
- If the customer on payment paypal click on the link "page cancels and returns to the site" the subscription is not deleted but rimanane signed with status "pending"
- If the customer pays when the payment has been successful subscription still remains in "Waiting".

Question 1: When a user clicks on the page paypal "link undo and return to the site" subscription should not be deleted?

Question 2: When the user has paid the subscription plan and the page paypal confirm payment subscription status should not become "Active"?

Question 3: I have noticed that if subscriptions with PayPal pagmaneto have not been paid and / or canceled in the subscriber profile displays a link to the invoice 00000. The invoice could not avoid until the subscription has not been paid?

Question 4: If the user subscription now with PayPal there is a way to recover the payment link so he can pay for it later?

The problems I am encountering, especially in the application 2 may be because I'm using the Test Mode?
 
Thanks for the support
