Hey Periwinkle Eagle, thanks for reporting this — we’ll need a bit more info to pinpoint what’s missing. Where exactly are you trying to update the card (Billing settings, during an upgrade/checkout flow, or from an invoice/payment page)? When you get the “missing required billing information” message, which details do you think it’s asking for but you don’t see a field for (billing address, company name, tax/VAT ID, etc.)? And is this preventing you from paying an invoice/renewal right now, or putting your sending at risk due to a failed/expired payment method?
