Additional Information

Using Trustly within an app
If you want to use Trustly within an app (without opening a separate browser session), you must utilize a Safari ViewController on iOS or Chrome CustomTabs on Android. Not using the operating system-native web views will cause the Trustly flow to break or not invoke a 2-factor authentication flow for the consumer after the bank selection.
