Hi, since some day, some of our users complain about an odd behaviour on the preapproval confirmation flow (adaptive payments - preapprovals API). While the great part of the users get everything fine as always, a few of them report that when they land on Paypal for the preapproval the login is prompted and once they correctly log with their paypal e-mail and password, instead to be correctly redirected to the preapproval confirmation page, as always, are redirected to the homepage of their paypal account. Obviously this behaviour makes impossible for the affected users to complete their preapprovals and it turns in a lot of orders loss. A lot of other users can correctly confirm their preapprovals with the same identical environment so it seems something connected to a specific user account but we can't figure out what.
Any help?
