Hello, jluros.
Thank you for notifying us about this. I'm here to assist in resolving the issue you encountered on the Merchant Service Center following the upgrade of your QuickBooks Desktop (QBDT) Mac.
At present, we have not received any reports related to the QBDT Mac Plus R11 version. If you upgrade to R11 again and the issue persists, I recommend reaching out to our Merchant Support team. They possess specialized tools that can access your account in a secure environment and investigate the cause of this unusual behavior.
To get their most updated contact information, please refer to this article: Contact Payments Support.
I'm also adding this article to answer the most commonly asked questions about QuickBooks Payments for future reference: FAQs for QuickBooks Payments.
If you have more questions about QuickBooks Payments or anything else, let me know by leaving a comment, jluros. I'm more than willing to assist. Take care.
