All of sudden today I am getting a rejection notice when e-filing with a pdf attachment.  It says the attachment must be a pdf.  The file is clearly a pdf & I have been filing all season & for many years with pdf attachments. 

I deleted the attachment & re-attached.  I renamed the file & re-attached.  Still getting rejected.

Is this something other people are encountering today or the last day or so?

Thank you.
