"Urgent: Serial Number Mismatch Error on Cloud Migration (Maximum Files Activated)"

Hi CazT, 

Thanks for laying out your issue and including the error message. 

This error usually needs to be sorted out from our support team's side, as it can happen when the file activation and the new subscription don’t line up properly during migration.

The safest next step is to get in touch with our support team so they can securely check the serial, subscription slot, and file activation linked to your account, then sort out what’s blocking the upload.

You can contact support through My Account by creating a ticket or by connecting to our Live Chat through MOCA, our virtual assistant. 

Regards,
Genreve

Hi CazT, 

I came across your post because our business is currently experiencing the same "Maximum number of company files activated" error after MYOB's recent migration.

We've been working with Support, Advanced Support and now the Developer Team for four business days without a resolution, and it's having a significant impact on our operations.

I appreciate that your situation may not be identical to ours, but I was wondering whether your issue was eventually resolved and, if so, roughly how long it took for MYOB to fix it?

Thanks in advance for any information you can share.
