Dear @Madleen

Thanks for reaching out,

Can I kindly ask you to answer the below questions:

1- Are you using our SDK tool? If not, did you review the signing documents? in order to ensure a full understanding of the signing process.  
2- What version are you using?  
3- What are the steps you are doing to sign an invoice?

Thanks,  
Ibrahem Daoud.
