Once your trial ends you will receive an email with instructions on how to resume as a paid subscriber. For uninterrupted access, you'll want to purchase a subscription prior to your trial ending.
Here is how you can purchase a subscription prior to your trial ending, and don't worry, you'll still have your first 14 days free!
Within the sidebar, click the Settings icon.
Then, click "Billing" on the left navigation. Within the Plan section, click the link, "SAVE 16.7%. Change to Annual Plan".
Fill in your credit card details and billing address. Then, select either an "Annual Plan" or a "Monthly Plan". Purchase an Annual Plan and you'll get 2 months FREE.
Click the button, "Purchase".
You're all done and your subscription will resume uninterrupted after the trial period has ended. You'll be taken to the below confirmation screen. You can close the tab and return to your web app.
