Live.GetLastVisitsDetails HTTP API not returning old data


Hi, we use the Live.GetLastVisitsDetails HTTP API to render data in our custom frontend. Recently we found out that Live.GetLastVisitsDetails is not returning data that was previously returned. Data (events with custom dimensions) that was recently there from february is now gone. After a bit of research we used this command (How do I tell Matomo to invalidate the past historical reports so they can be re-processed from the logs? FAQ - Analytics Platform - Matomo) to reprocess the data. But now all data is gone, even that from yesterday. Has this todo with archiving? Is there some way to “un”-archive the data? Or is there a parameter for Live.GetLastVisitsDetails to get all the data, even the archived one?
