.NET SDK 3.3.9 - GenerateEInvoiceQRCode Issue!

Greetings,

When generating GenerateEInvoiceQRCode after signing the B2C invoice it generates the QR without the datetime causing the ZATCA app not reading the QR while other app it reads it without the datetime!

GeneratedSignature in GetIssueDateTimeString always null!

i don’t know what is wrong with your qr but i checked it by my phone

it works 2 times from 10 Trys
