Apple and Google do not allow sharing of subscriptions across devices; however, there is a workaround for this.
Please visit www.tripwizard.rvlife.com and log in using the same credentials you use for the app. RV LIFE Trip Wizard is included with your RV LIFE Pro subscription.
After logging into RV LIFE Trip Wizard, the subscription will be linked to your email address. On your other devices, open the RV LIFE app, navigate to the Profile & Account page, sign out, and then sign back in. This will enable the subscription to be shared across your devices.
