I used the developer portal simulation and generated a CSR from the SDK with the VAT number on the portal and -sim flag . I also used the simulation API, and everything went smoothly with a response status of 200. However, I couldn’t find any invoices or devices added to the portal.

Hi Aturkistani,  
We are facing the same problem on our end. The statistic page, sometimes it shows the results, but most of the time it says “There are no invoices submitted in the last 12 months.”  
Your immediate response would be highly appreciated.
