# Upload Issues

> Fix common upload problems on Circo, from stuck uploads to format errors.

If your upload is failing, pausing unexpectedly, or getting stuck, follow these steps to resolve it.

## Before you start

Check these basics first:

* **Connection**: Use a strong Wi-Fi connection. 4G or higher is recommended if you're on mobile data.
* **App version**: Make sure you're running the latest version of Circo. Outdated versions can cause upload failures.
* **File format**: Circo supports **MP4** for video. MOV is also accepted. Other formats may not upload correctly.

<Note>
  Circo uses resumable uploads. If your connection drops or you close the app, your upload pauses automatically and picks up exactly where it left off when you return — no need to restart from scratch.
</Note>

## Tips for a smooth upload

* Keep the Circo app open and in the foreground while uploading. Switching apps may pause the process.
* If you switch between Wi-Fi and mobile data during an upload, expect a brief pause before it resumes.
* Large videos may take additional time to process after the upload completes. You'll receive an in-app notification when your Drop or video is ready to publish.

## If your upload is stuck

<Steps>
  <Step title="Restart the app">
    Close Circo completely and reopen it. Check if your upload resumes from where it left off.
  </Step>

  <Step title="Retry the upload">
    Navigate back to the upload screen and retry. Circo's resumable upload will continue from the last checkpoint rather than starting over.
  </Step>

  <Step title="Check your file">
    Confirm your video is in MP4 or MOV format. Files in other formats will fail to upload.
  </Step>

  <Step title="Contact support">
    If the problem persists after restarting and retrying, contact the support team. Include a screenshot of any error message you see to help resolve the issue faster.
  </Step>
</Steps>

<Warning>
  Do not force-close the app repeatedly during an active upload. This can interrupt the resumable upload session and require a full restart.
