Hi, we are trying to implement the custom dimensions via Google Tag Manager but they are not being tracked, the custom dimension page for the JSESSIONID in Matomo says: There is no data for this report.

But it is not tracking. We are able to track just by sending a separate event, but then we have the data in the Events tab.
What are we missing here?
