Bug description

Since updating to Nextcloud Hub 9 (30.0.1), email notifications are no longer sent when I share folders via email. The SMTP configuration is correct, as test emails are sent successfully. I’ve also tried deleting and reconfiguring the SMTP settings without any improvement. However, on my mail server, I can see that no emails are sent whenever a share with email notification is created.

Steps to reproduce

1.	Update to Nextcloud Hub 9 (30.0.1).
2.	Set up SMTP email configuration (confirmed working by sending test emails).
3.	Attempt to share a folder and select the option to send an email notification.
4.	Check the mail server logs for any outgoing emails.

Expected behavior

Email notifications should be sent to recipients when a folder is shared via email.
