I just updated my iPhone 7 to iOS 13.1 the other day and now all of my daily emailed reports are showing up on my phone as dots instead of ticket sales and ticket counts. The emailed reports look fine on my Outlook. Not sure if this is an Apple issue or a Tessitura issue. So odd. Any thoughts?
So no one else has to, I decided to suffer through phone support and verified that this is an issue known to Apple engineering, and theoretically will be resolved in a future iOS update.
That said, the root cause does appear to be that the PDF generation functionality in PowerBuilder 2017 (the framework on which Tessitura 15 is built) does not output fully spec-compliant PDFs. Using a validation tool like https://www.pdf-online.com/osa/validate.aspx, a PDF generated by Tessitura 15+ throws validation errors like the following:
(whereas a PDF output by Tessitura 14 using the Ghostscript library validates as conforming to pdf1.4).
