Currently, when donors attempt to update their card number on pages with the [give_subscriptions] shortcode, two things happen that shouldn't:
  1. The card does not update at stripe.
  2. The legacy page redirects automatically to the donor dashboard page, even if the setting in the dashboard is to use legacy pages.
You have to navigate back to the legacy page to even see the error, which is vague and not also logged in the logs.
