## Description
### Stripe
- Settings have been modified to "Cancel" the subscription if all
attempts to charge an invoice fails. The previous configuration was to
set the subscription to "Past Due".
### Museum
- Updated our Stripe workflow to use `PaymentBehaviorAllowIncomplete` in
case of SEPA payments
- Fixed the issue caused by us spawning unnecessary subscriptions when a
customer tried to renew their expired subscription
- Removed the email that was being sent out when a Stripe subscription
expired. We will have to run our own cron to send a notification and
perform necessary clean up. When payments fail, we will still send a
notification to intimate the customer that their account is on hold.
### Mobile
- Fixed the dialogs and error messages on the payment page
## Tests
The following cases were tested for SEPA, Credit Cards, and Credit Cards
with 3DS.
- [x] Purchase
- [x] Success
- [x] Failure
- [x] Renewal
- [x] Success
- [x] Failure
- [x] Upgrades
- [x] Success
- [x] Failure
- [x] Cancellation
- [x] Resumption post recovery
## Note
These changes are likely to break in the event of some corner cases we
haven't thought of. But this will land us in a state that is better than
where we are right now in terms of collecting payments for expired
subscriptions and those via SEPA.
