Here's how you install a test version...

 

1. Download the APK file containing test app version.

2. When prompted, click Install. If you are not prompted even after the download is over, simply find the downloaded file in your download folder and click on it.

3. Start using the app like you normally would.

4. To report a bug, ask a question or share a suggestion, use the "Send Feedback" link within the side navigation in the app.
   
   
5. If you have any issues installing the test app version, try uninstalling the existing Playerline app on your phone first, and then try installing the test version once again.
