# Adjust Id Empty Issue
### Overview
The SDK Mismatch issue related to Adjust can occur when the credentials on the Lion portal do not include the necessary App Token required for the Adjust SDK to function correctly. This issue is particularly common for older games on the Lion portal, where the Adjust App Token wasn’t initially required. Starting from version 4.37.0 of the Adjust Unity SDK, the App Token has become essential for proper SDK integration and operation.

2. **Navigate to Your Adjust Developer Page**: You will need to select your app where you can see the app token and copy it. Go to:\
`App Information → App Details → App Token`.\
Clicking the **Adjust Developers Dashboard** will take you directly to the Adjust dashboard (if you have access) at:\
3. **Insert Token and Press the Button**: Enter the copied App Token into the popup and press the **Continue** button. This action updates the Adjust App Token settings with the correct token, resolving the mismatch issue.
