Hi @Christian Punknown, is this a trial license or a paid license? If it’s trial, we can check and see if it’s still valid. If it’s a purchase license, that error usually means it is not being entered correctly- it is case sensitive. Another thing to check is to make sure you are entering the app id exactly the way it is listed in your welcome email. They have to match exactly.

If you are running the sample app, you need to remove the default SDK license we have there.

If you have checked all that, let me know and I’ll need to see some examples of where you are entering it in your code.
