Hello bstaeuber,

Thank you for raising this, are you testing this on a local environment? or the deployed app on

Best regards,

thanks for reaching out to me, I am using localhost. Maybe it needed a while that the license got updated, but I am not seeing the trial watermark anymore. Very good! I think we can close the ticket here.

Thanks for the support
