A lot of people hate in-app support. Revolut (similar concept to N26) for example really screwed this up, someone drank too much AI and bot framework koolaid at a conference and now millions of users (and arguably the pecetion of the business) suffers. Having a email support method is a must.
Yeah I'm not talking about chatbot style support, but real live chat support. They have it on the web UI, it would be nice to have in the app again. But I'd settle for a contact form in the app like they used to have.
Isn't Revolut a pre-paid debit card though? N26, in contrast, is a bank.
EDIT: oh, I see that "On 8 February 2017, Revolut launched UK current accounts, enabling its customers to get a personal IBAN" on their Wikipedia article.
