When you need to change your card details - you can update your details through the Camplify dashboard. 

  1. Go to your dashboard
  2. Click on your profile picture
  3. A drop down will appear with "Premium Subscription"
  4. Click this and then a pop up will appear from Chargebee - the payment portal
  5. Log in with your Chargebee information - or use forget password if you can't remember
  6. Then you will be able to see your card details and subscriptions
  7. Save your changes
Then give Camplify a quick call to let them mark this as the primary card, otherwise, next month it will try the old card again.
