If you can log in on one device but not another, try the following:
Make sure you're using the same email address on both devices.
Check your internet connection on the device that's having trouble.
Request a fresh confirmation code — old codes expire quickly.
Update the Playbook app to the latest version on the device with the issue.
Note: Logging in with a different email address on the second device will create a new account without an active subscription.
