Every citizen in Sweden uses an app called BankID (https://www.bankid.com/en/) to authorise themselves to various banks, government and other services. This app is a must to be able to do certain things on mobile phone. As of now, mobile version of Orion doesn't know how to deal when the site tries to open bankid://
which makes it impossible to access certain websites.
To test this, go to a website such as https://www.telenor.se/mitt-telenor/ and click on "BankID" --> "Öppna Mobilt BankID". Orion will try to look for an app for a second and then fail saying that it doesn't know how to deal with that URL.
