Hello @Vekii46 welcome to our Community, I'm happy to help you with this!
I did a quick search on your email address right away and saw that your account was still linked to an old/inactive subscription, which is why you are seeing this message. I have just deleted the account for you and also disconnected the number.
You can now create a new account via our website: https://www.odido.nl/my/registreren and then add your subscription, then it should work! To be sure, please delete the app and download it again, so you will also have the latest software.
Will you let me know if it works? I would love to hear from you!
