# PDFプレビューの表示に時間がかかることがあるのはなぜですか？

これは、作業中の文書にエラーがあるためかもしれません。プレビューは、文書のコンパイルが正常に成功した場合にのみ更新されます。そのため、エラーがあるとプレビューは更新されず、エラーが修正されるまで最後に正常にコンパイルされた内容が表示されたままになります。

プレビュー右上の「error」という単語にマウスを重ねると、文書内のエラーを確認できます。たとえば、よくあるエラーとして、数学記号をドル記号で囲む必要があります。たとえば、 $$\phi$$ 単に \phi ではなく。

エラーが解決されてもPDFプレビューが更新されない場合は、 [お知らせください](https://www.overleaf.com/contact) こちらで確認いたします。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/ja/narejjibsu/163-why-does-it-sometimes-take-a-lot-of-time-to-show-the-pdf-preview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
