how can I get data from a salesforce object sync? I can see the field structure that has been ported over and how many lines of data have been transferred, but I can't seem to find the data anywhere. Where can I get the data from this data row?
You should move the question to Products "Community" is for issues with the Marketo Nation (this website) itself -- and yes, this is confusing.
Marketo doesn't allow you to access synced objects as raw data within the UI. You can use them in Smart Lists (every CO gets its own filters and triggers) and you can also read all their properties using Velocity (Marketo's powerful, Java-like scripting language for emails).
