Today, we receive push notifications for new episodes from all shows, even the ones that are hidden. We should either not receive push notifications for a show if it is hiddent, or at least have a setting not to receive those notifications.
Thanks for the valuable feedback. This could happen when the reminder is already in the pipeline. But it should be an minor task to exclude hidden shows from all push notifications.
I will implement this feature in the new version 2.2.
