When trying to log in the app wouldn't send the SMS for the verification code (despite all the authorization) blocking the process. But there is a simple workaround.
1) with the EasyPark app closed open the browser and go to the easypark login page;
2) enter phone number and await the verification code;
3) AFTER you receive the sms open the app and enter the code just received;
4) the app will be fully functional.
Hope this helps
