How do I change the subscription's card?
The owner opens Martialnote plan > Manage my subscription and changes the card in the Stripe portal. The new card is used for the next charges. This is also the way to fix a failed charge: the Pay button is not offered in that case. Martialnote never sees the card. An instructor cannot change it.
