My Matrix is empty — why?

Short Answer

An empty Matrix usually has one of three causes — the time range is too tight, a filter is too restrictive, or there are no Updates in the selected folder. Open the Filters popover, click Reset filters, and pick a longer time range.

Details

Check the time range. The Matrix shows the last seven months by default. If you set a very tight range (for example a single week in the past), the Matrix can end up empty. Under Time range click one of the presets (“last 30 days”, “this month”, “year to date”) or widen the range manually.

Check the filters. In the Filters dropdown, a red number shows how many filters are active. Click Reset filters to clear them all. Most common filter traps:

Ownership set to “own only” or “exclude competitors” — cuts out a large share of the sources.
Source tags or Update tags selected — hard restriction to tagged sources or topics.
Channel types narrowed — for example LinkedIn only, then every other channel is missing.

Check the folder filter. By default only the Inbox counts. If your team has already reviewed and saved every Update, the Inbox is empty. Switch to Saved or turn on both folders (Inbox + Saved).

Check whether any Updates exist at all. If you just set up sources or you are tracking sources with little activity, it is possible that little or nothing happened in the range. A quick look into the Inbox clears that up.

When that does not help

Check whether the selected View can in principle produce data. Views built on update tags (for example Topics over time) stay empty if your Updates carry no tags yet. Switch to a view without a tag axis, for example Sources over time.

If the Matrix stays empty, contact support — it could be a data issue in the workspace.
