Here is how to access the payment portal:
Log in to your Submittal account.
Click on Settings in the top navigation menu.
On the "Account Settings" page, select Payment from the sidebar menu.
In the "Subscription Details" card, click the orange Manage Subscription button.
This will open a link to Stripe's secure payment portal where you can cancel your plan.
If you cancel, your subscription will remain active until the end of your current trial or billing period.
