During my last visit to Mumbai I managed to not use any cash but only my credit card.

My problem is neither Uber nor Ola are accepting my credit cards.
In the Uber app, I can register them, but can't use them to pay.
In the Ola app, as soon as I want to register a credit card, I get the error message "Failure! Sorry, something went wrong. Please try again."

I don't have any problems with Uber or other apps in other countries, like Vietnam, Thailand, Singapore etc.

I will have another trip in February. Do you usually pay cash (both uber or taxis)?
