I try to export Xrechnung documents and send them to customers via e-mail in Business Central. I completed all the required setup for exporting and sending Xrechnung documents:
- Document Sending Profile
- Workflow
- E-Document Service
- Filling necessary fields for specific customer that I will send the document
- Filling necessary fields for my own company
I create the Sales Order, then I click Post & Send, but the email page that appears normally in BC version 27.2, does not appear in 26.2.
Page that appears in 27.2:

Did anyone manage to send e-documents via email in BC version 26.2 or earlier versions?
If more information needed, please say so.
Any help will be appreciated!
