When making an appointment, birchpress doesn’t send any email notifications (possibly blocked by ISP). I tried to sole this issue by installing WP Mail SMTP. All other wp emails are now set to use WP Mail SMTP / Gmail API sync. All wp email notifications are now working but not birchpress.
I noticed that birchpress doesn’t use default wp_mail() function to send emails?
I there a way to set birchpress smtp function, a php code etc?
