 # Common issues and resolutions for PowerApps
+This article lists some common issues that users might encounter while using PowerApps. Where applicable, workarounds are provided.

 ## Recently added/changed
+1. **Combo box controls in galleries**
+
+    When you use a **Combo box** control inside a gallery, its selections are not maintained when the user scrolls the gallery. This is not an issue if you use a **Combo box** control inside a gallery that doesn't scroll. A workaround is not currently available.

 1. **Using a custom image as an app icon**
 
 	In PowerApps Studio for Windows version 3.18043, you cannot upload a custom image to use as an app icon. To work around this issue, use [PowerApps Studio for web](https://web.powerapps.com) to upload a custom image. Alternatively, you can use one of the icons included with PowerApps Studio for Windows and customize the background color.
