Hello
I am trying to attach multiple large files (i.e. pdf, Docx) using Graph API by creating an upload session.
But Receiver received only the first attachment as I think while uploading bytes of the second file upload session is not being created.
I am using below link for reference:
So if anyone can guide with this scenario will be appreciated.
And please let me know if you need any detail to guide me with this.
