In our test runs, the pending clients not associated with a product, are not receiving the pending invoice notifications. How do we fix this? Example of one such user https://gyazo.com/517ba4fbdd1f06a12c9ec42fce01e588
aMember send pending invoice notification to user who began subscription process (create invoice) but did not complete it for some reason (do actual payment). As I can see on your screenshot this user have not pending invoices so he did not receive such notification.
