Hi there!
So after many perplexing tries at enabling the Progressive Profiling cloud component, we contacted Eloqua support and found out there is a bug that effectively permanently disables this module.
Upon clicking "Enable" the Eloqua wheel spins for a moment (sometimes a few), but then nothing happens. At first we thought it might be due to a user not having administrator privileges, but soon found that was not the case.
We opened a support ticket about the issue and hope to be notified when it is fixed. Wondering if anybody else is experiencing this?
