In the last week for some reason the email notifications are no longer being sent to the client. They are however being sent to the applicants. Looking through the logging I found this:
2023-09-07 10:20:14.757150 - DEBUG → GFAPI::send_notifications(): Notification is disabled by gform_disable_notification hook, not including notification (#5ac525769186e - Client Notification).
2023-09-07 10:20:14.757291 - DEBUG → GFCommon::send_notifications(): Processing notifications for form_submission event for entry #558: Array
 => 649a146c82df6
(only active/applicable notifications are sent)
2023-09-07 10:20:14.757364 - DEBUG → GFCommon::send_notification(): Starting to process notification (#649a146c82df6 - Send email confirmation to Applicant).
2023-09-07 10:20:15.651922 - DEBUG → GFCommon::send_email(): Aborting notification (#649a146c82df6 - Send email confirmation to Applicant) for entry #558. The gform_pre_send_email hook was used to set the abort_email parameter to true.
2023-09-07 10:20:15.681740 - DEBUG → GFCommon::send_notifications(): Sending notifications for entry (#558) completed in 0.924451 seconds.
So for some reason it is disabling notifications to the Client even though nobody added this hook to any file or changed anything. The email is processed correctly to the form applicant as noted and you can see in the log file. The client notification is ACTIVE.
I can see under each entry that it is only sending to the applicant and not to the client as well.

Any idea if this is a bug in the latest code release that could have changed this as we have not changed any code or anything else with our forms or website since this broke.
