# When an app doesn’t work

Most app problems come from three things: an update waits for a decision, your package no longer includes the app, or its setup isn't finished. The **Needs attention** filter in **My apps** shows every app where something is open.

> **Type:** troubleshooting
> **For:** anyone who installs, uses, or looks after apps. Many solutions need the Owner.
> **Prerequisite:** access to **Apps**
> **Where in the portal:** **Apps** › **My apps** › **Needs attention**

## A widget can't be placed, or a scene doesn't play

| Symptom | Cause | Solution |
|---|---|---|
| The app's tile in the scene editor shows **Update waiting** | An update waits for a decision. Scenes that use the app keep running. | Click the tile and decide, see [When an app update is waiting for your decision](/apps/app-update-decision). |
| The app shows **Not in your package** | Your package no longer includes the app, or its booking ended. Settings and data stay. | Click **View packages**. A larger package or a new booking unlocks it at once. |
| A scene shows **Blocked** | The scene uses an app your package doesn't include. It drops out of programs and playlists. | Click **Remove app from scene** and publish, or change your package. |
| A widget shows no data | The app's setup isn't finished, such as a missing location or menu. For Posts, Table, Reviews, Dashboard, and Warning, a data source is missing or delivers nothing. | Complete the open steps under **Setup** on the app's **Overview** tab, see [Look after installed apps](/apps/my-apps). You check a data source under **Data sources**, see [Data sources: options, intervals, and states](/content/data-source-reference). |
| An app content in the library shows **App not installed** | The app was uninstalled. The content stays, and the display skips it. | Install the app again, see [Install or book an app](/apps/install-app). The content then runs again by itself. |
| An app content in the library shows **Widget not available** | The app no longer knows this widget. | Create a new app content from the app's current widgets, see [Create, configure, and maintain app contents](/content/app-contents). |
| **Not everything runs on this display** | The app doesn't support the device type of this display. | Check **Runs on** in the app's listing, and assign this display content without the app. |
| The palette says **No apps installed** | No app with widgets is installed. | Click **Discover apps**, see [Find the right app](/apps/discover-apps). |

## Installing doesn't work

| Symptom | Cause | Solution |
|---|---|---|
| **Ask the owners to install** instead of **Install** | Only the Owner may install. | Send the request, see [Install or book an app](/apps/install-app). |
| “This app is only included from a larger package.” | Your package doesn't include the app. | Click **View packages**. |
| “This app is paid and must be booked first.” | The app is an add-on. | Click **Book and install**. |
| “No further apps can be installed at the moment.” | No further app fits in. | Uninstall an app you don't use. The **Not in scenes** filter finds one. |
| “The permissions of the app have changed. Please reload the page.” | The app changed while the dialog was open. | Reload the page and check the permissions again. |
| “We have switched the app off for the time being.” | The app is paused for everyone. Settings and data stay. | Wait. The app comes back with its data. |

## Messages on the app's page

| Symptom | Cause | Solution |
|---|---|---|
| “The interface of this app could not be loaded.” | The data area couldn't be opened. | Reload the page. If it persists, contact us. |
| “This app provides no interface for this data area.” | The app maintains this data itself. | Nothing to do. |
| “Installation failed” or “Uninstall failed” | The action didn't reach us. | Try again. If it persists, contact us. |
| A button is grayed out | Your role doesn't allow it. Installing, updating, and removing apps is up to the Owner. | See [No access, a grayed-out button, a locked area](/help/access-troubleshooting). |

Problems with a single app, such as the news or the pharmacy duty, are on that app's page.
