I apologize in advance; I did editorialize the title to make it easier to understand than what was originally used. Their own title made the reader assume this was about a problem with the Samsung Shop app itself.
In short: There is a national identity app in Sweden called BankID. Close to 100 percent of the population have this installed. Samsung decided to use the same url scheme for their Shop app, meaning that no Swedes with iOS and the Samsung Shop app installed can longer use the BankID to identify when using other apps and websites.
