If you define a test device and select a network in the Test Mode section of your MAX account, when that device makes a MAX ad request MAX will request the ad from the network you selected with that network’s test mode enabled. The device will also receive detailed device logs.
When you turn off Test Mode on your device, ad units will revert to using the configuration listed in the MAX Ad Units page. In addition to using Test Mode in the dashboard, AppLovin recommends that you use Mediation Debugger Test Ads as you quickly test the integration on your devices.
Enable Test Mode
Choose the Test Network you would like to see ads from and click ✔ Save. When the save completes, all MAX apps associated with your account will start receiving test ads from the selected network.
Disable Test Mode
To disable test mode on your device, select MAX > Mediation > Manage > Test Mode. Find your device in the list of MAX Test Devices and, in its row, hover over the green dot in the Status column. A pause icon (⏸️) button will appear next to the dot. Click that button. Then, in the Pause Test Device dialog that appears, click ✔ Yes. Your device will then revert to receiving ads based on the ad unit configuration listed in your MAX Ad Units page.
