Recurring payments have been intentionally blocked by the banking regulator in India by requiring 2FA for every online transaction to prevent abuse/fraud. It is a known pain intentionally traded off - hopefully will get fixed at some point. I think the issue with international cards is also likely linked to online transaction 2FA policy. Some American banks don't implement 2FA and that's likely the reason they fail. I've never had a problem with my Singapore card.
