As a Playground Sessions user, you're allowed to access Playground on up to 2 devices at any time.
If one device becomes unusable after you've installed and used Playground Sessions on it, simply:
- Visit your account's installation page here: https://www.playgroundsessions.com/my-account/installations
- Click on the "De-Activate" link next to the device that you'd like removed from your account
Once the device has been removed, you're then free to replace it by using Playground Sessions on another device.
