In case of an expiring or lost credit card, you can update your credit card details through the billing portal in Hypervault.
Go to 'License & Billing' in the upper right corner
In the first block from 'Current plan', you'll notice the link 'Manage plan' in blue. Click on this to edit your Subscription details.
A modal will appear with the number of seats. Click on 'Edit Subscription Details' on top of the modal. This will bring you to the Subscription Details.
The subscription details contain the billing amount, your workspace and how it's paid. To change your credit card, click on 'Paid via'
Enter the new credit card details and click on 'Update'.
From now on, your billing will happen on the newly provided card.
