Hi Anthony, I have a few questions to help determine what's going on:
Are you receiving any error messages when you load the workbook in Tableau Reader?
Were you able to open the workbook in Tableau Reader 10.4? (if you ever had occasion to try?)
Are you able to open any other workbooks successfully in Tableau Reader?
Are you able to share the .twbx here so we can take a look?
No error message is received when loading the workbook into Tableau Reader.
I did not attempt to open in Tableau Reader 10.4 as I don't have it on my computer and cant' seem to find a link to download version 10.4. Seems the Tableau website only has the most current version, 10.5.
Yes I am able to open other workbooks successfully in Tableau Reader.
I am unable to share the .twbx in question because it contains sensitive information.
