@EMartin these error messages would need to be translated for the languages in the big bundle. I feel like we could go ahead with a 1 hour test and see if people run into these and not impact the longer term plans for the bundle.

@CDenes_WMF I don't think these translations are super high priority or time sensitive. The english strings will be on payments wiki and volunteers could end of working on these before we do any further testing. So there might not be that much work to do here long term.

if we are using adyen's own translation, here are the list of field we need translation:
"donate_interface-expiry-date-field-placeholder": "MM/YY",
"donate_interface-cvv-placeholder-4-digits": "4 digits",
"donate_interface-cvv-placeholder-3-digits": "3 digits",
"donate_interface-error-msg-expiry-date-field-invalid": "Invalid expiry date",
"donate_interface-error-msg-invalid-cvv-format": "Invalid CVC / CVV format",
"donate_interface-error-msg-incomplete-field": "Incomplete field",
"donate_interface-error-msg-field-not-valid": "Field not valid",
"donate_interface-error-msg-invalid-card-number": "Invalid card number",
"donate_interface-error-msg-card-number-do-not-match-card-brand": "Typed card number doesn't match card brand",
"donate_interface-error-msg-unsupported-card-entered": "Unsupported card entered",
"donate_interface-error-msg-card-too-old": "Card too old",
"donate_interface-error-msg-date-too-far-in-the-future": "Date too far in the future"

p.s. LV is missing "donate_interface-credit-card-expiration"
