# Troubleshooting

> Find fixes for common problems with the Scope extension, Lectra, Polya, and signing in.

Start with the guide for the app you're using. Each one covers the most common problems and how to fix them. Problems that involve more than one app, such as signing in or moving files between apps, are covered on this page.

</CardGroup>

## Sign-in and account problems

<AccordionGroup>
  <Accordion title="I can't find my files or courses after signing in">
    You might be signed in to a different account than before. Each app shows who you're signed in as:

    * **Scope extension:** click the Scope icon in the Chrome toolbar, and then click **Settings**.
    * **Lectra:** tap your profile picture in the library to open **Settings** > **Account**.
    * **Polya:** your name and email are at the bottom of the sidebar. On a phone, they're in the menu at the top of the screen.

    If the apps show different accounts, sign out of the one that's wrong and sign in with the right Google account. To learn more, see [Your Scope account](/get-started/account).
  </Accordion>

  <Accordion title="I signed in to Lectra with Apple, and the other apps can't find my account">
    Only Lectra offers Sign in with Apple. The Scope extension, Lectra for Mac, Lectra Receiver, and Polya sign in with Google, so they can't reach an account you created with Apple. To use Lectra with the other apps, you need an account you sign in to with Google. Before you switch, [contact support](/resources/get-help) so you don't lose your backups.
  </Accordion>

  <Accordion title="Polya says sign-in didn't go through">
    Go back to [askpolya.com](https://askpolya.com) and sign in again with **Continue with Google**. If you see the message again, [email Polya support](/resources/get-help#polya).
  </Accordion>

  <Accordion title="The email and password option in Polya doesn't work">
    **Sign in with email and password** works only for accounts that already have a password. You can't create an account with it. Use **Continue with Google** instead.
  </Accordion>

  <Accordion title="Google sign-in in the Scope extension doesn't finish">
    Try again from **Settings** > **Sign in** in the Scope window, and make sure you finish the Google window that opens. If it still fails, update the extension from the [Chrome Web Store](https://chromewebstore.google.com/detail/scope/bamoelobnoepklagbcokjnlipfhcfdbb) and try again. For more fixes, see [Troubleshoot the Scope extension](/chrome/troubleshooting).
  </Accordion>
</AccordionGroup>

## Problems moving files between apps

<AccordionGroup>
  <Accordion title="PDFs I send from Chrome don't appear in Lectra">
    Check each of the following:

    1. The Scope extension and Lectra are signed in to the same Google account.
    2. **Send to Lectra** is turned on in the extension's **Settings**. It's off until you turn it on.
    3. In Lectra, open the **Scope Inbox** in your library. Files from Scope land there, sorted by course.
    4. If the inbox is empty, tap **Check for New Files**. If Lectra says it couldn't check, check your internet connection and try again.

    In Lectra 10.0 or later, a document that's still downloading shows **Arriving…**. If the download fails, the document says so; tap it to try again. For more fixes, see [Send files to Lectra on your iPad](/chrome/send-to-ipad).
  </Accordion>

  <Accordion title="The PDF I attached from Lectra doesn't have my markup">
    Open the document in Lectra and wait for it to finish saving, and then attach or send it again. To learn more, see [Export and share](/lectra/export-and-share).
  </Accordion>

  <Accordion title="My Mac doesn't appear in Lectra">
    Make sure Lectra for Mac is installed, open, and signed in to the same Google account as Lectra on your iPad. For setup steps, see [Lectra for Mac](/lectra/mac).
  </Accordion>

  <Accordion title="Select from Lectra doesn't appear on an upload page">
    **Select from Lectra** appears on Canvas assignment upload pages and Gradescope upload forms. It needs the Scope extension signed in, with **Send to Lectra** turned on. On Gradescope, the Lectra Receiver extension can add it instead. If the page was already open when you changed a setting, reload it. To learn more, see [Send files to Lectra on your iPad](/chrome/send-to-ipad).
  </Accordion>
