Hi The_Doc
I'm unsure about what that feature or online facility was. It could have been MYOB Advisory - which would be attached to the MYOB Partner Dashboard. This allows Partners to generate reports and analyse businesses within their Dashboard. There are 20+ charts that can be generated with that process.
The other thing it may have been would have been Power BI integration. With Microsoft ceasing the content pack integration for that in 2019 we no longer support or offer that as an integration method.
Apart from that, if you can remember the name of that dashboard or the MYOB product/service we'll be happy to look into that and provide additional information if required.
