If you can still retrieve traces and annotations via the API but see 0 traces in the Phoenix Cloud UI, this is likely due to the default time filter in the UI (often set to the last 15 minutes), not data loss. Adjust the time range filter in the UI to a broader window (e.g., "All time" or a custom range covering when you logged the traces) and your traces and annotations should reappear. This is a known UI behavior and not an indication that your data is missing or deleted—your data remains accessible via API and is still present in the backend according to <https://github.com/Arize-ai/phoenix/issues/6016|GitHub issue 6016>.
If changing the time filter does not resolve the issue, try clearing your browser cache or refreshing the page, as UI state or caching issues can sometimes prevent data from displaying correctly. If the problem persists after these steps, it may be a UI bug, and you should report it to the Phoenix team for further investigation as suggested in <https://github.com/Arize-ai/phoenix/issues/6016|GitHub issue 6016>.
