You find a button in the "Future" for the investment. There you will find an overview of the investment and can continue with "Invest now". After you have checked your data, you can continue and will be redirected to WIWIN.
If you already have a WIWIN profile, the app may indeed display an error message when you try to invest, because the existing WIWIN profile is not automatically linked to our app. In this case, you also have the option to complete the investment directly via WIWIN.
Alternatively, we can contact WIWIN to have your existing profile with the same email address linked to the app, but this would definitely take a bit more time. In that case, please send us an email at support@tomorrow.one.
