Hi Antz72,
Since you're experiencing the issue with sending customer statements, I recommend clearing the AccountRight cache by following the steps here.
Ensure as well that your email setup in MYOB is properly configured. This includes checking if the email addresses in the customer profiles are correct, and that MYOB is linked to your email server without any disruptions.
Since you've previously had success sending 8-10 statements at a time, continue with this method for now. Sometimes, sending large numbers of statements at once can cause the issue, which might explain why only a few are being sent.
If the issue persists, please reach out to our live chat agents through our virtual assistant MOCA or submit a case via MyAccount.
Regards,
Sai
