How to join the Beta program?

If you want early access to the app new features and bug fixes, you will need to install the BETA version of the app.
In order to do so you need to go into the app description page on the Google Play Store, scroll down and then press on the Join BETA button.
You will then receive Beta versions via Play Store updates and once the final version is available, you will automatically receive it on your device.

You can leave the Play Store the same way you joined at ay time.
