# App losing connectivity

## Problem

When using the Mobile app, it is losing connectivity or running slow with a spin icon when saving.

## Explanations

### Poor or unreliable data connectivity

If your signal frequently drops to two bars or less, this can cause timeout issues connecting to the server.

#### Solution

Run the app in [Offline mode](/concepts-and-fundamentals/mobile-app/working-offline.md) and synchronise back to the server when you have more reliable connectivity.

### Device OS not up to date

If your device's Operating System isn't up to date, it can cause problems with the app's ability to maintain a consistent connection.

#### Solution

If you are able to apply updates to your device's operating system, go to your device's system settings and apply updates. Refer to instructions for your device and operating system on how to apply updates.

### App version not up to date

Older versions of the app may lack improvements that make the mobile connectivity more reliable.

#### Solution

Check the app store for updated versions of the app.

## 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://docs.cw.crisisworks.com/security-and-support/faqs/troubleshooting/mobile-app/app-losing-connectivity.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.
