I don't know if it was the case in other countries but in Belgium a very popular app used to store loyalty cards was bought by Klarna. It was not really clear that you could continue to use the old app for a while and not switch to Klarna. So I know a lot of people that just installed the app just to be able to have access to their cards.

We get a lot of advertising for it here in Belgium and tons of webshops support it, sadly. What a trash company.
