I locked some content with the [newsletter_lock] shortcode. When sending the welcome email with a link to the locked content the user can unlock it and read the content – this works without problems, because the “newsletter” cookie is set.
When I send a new newsletter with a link to a new article with locked content the subscriber can read it – but only in the browser he used for the welcome email (because the cookie is still set).
But when the user opens the new link (with the locked content) in a different browser without the cookie the content is locked!
How can I configure the plugin that all new articles with locked content can be visible by the subscribers, independent of the browser or when the cookie was deleted?
I tested all configurations, have read the manual, but can not find a solution!
