very new to Filemaker community, so be gentle.
I built an invoice database to be used on a ipad mini (Generation 1) on FM Go 13.
You create an invoice, it has a portal in it to add line items. The line items are tallied up. When the invoice is complete, you push the "email invoice" button, until very recently, the app worked perfectly. Now intermittently when I send the email, the pdf attached has missing information, all the records are blank.
The only thing I can see that has changed recently is that we upgraded the ipad mini to iOS 9, coincident, I don't know?
