On the stats page click the reason's row (or its View link). A pop-up opens titled with the reason's name, with a line reading "All subscriptions that were [Paused / Canceled / Paused or Canceled] for "<reason>" reason!" — it lists only the type(s) that reason is actually used for (e.g. just "Paused" if the reason is only offered in the pause flow). If the reason requires a justification, the justification title is shown as a sub-heading and the table includes an Answer column (hidden otherwise). Columns: Sub ID (links to the subscription), User (links to the customer), Answer and Type (Paused/Canceled badge). If nothing was recorded yet you see "No data for this reason!".
