Using Invoice Ninja v5.3.89 customers can only add credit card as payment method in customer portal. I use Stripe as payment gateway and enabled some other payment method (e.g. SEPA) too.
When there is an unpaid invoice for the customer, it works and he can pay with the other payment methods and save them for later use (customer portal → invoices → pay invoice → add payment method).
But he can’t add a new payment method, except credit card via customer portal → payment methods → add payment method.
Is that a bug or am I using it wrong?
