I'm here to make sure you never experience the same thing again, Greg142.

Good news, the investigation Attachments not sent on the Invoice or Purchase Order with the new experience have been resolved. When adding an attachment to a Sales or Expense form, you'll see a checkbox for "attach to email." Once that box is checked, it will include your attachment in that email. 

If the same thing happens, we can log in to your account using an incognito browser. Private browser prevents saving cache and cookies that sometimes cause errors when running frequently visited websites. Here are the useful shortcut keys you can use to access one:

• Ctrl+ Shift + N for Google Chrome 

   

• Ctrl + Shift + P for Mozilla Firefox 

   

   and Microsoft Edge 

   

• Command + Shift + N for Safari 

   

If it works, return to your default browser and clear its cache. Every so often the cache becomes overwhelmed with older data which can potentially cause viewing and performance issues. Clearing it will refresh the system, and you'll be able to work with a clean slate. Switching to another compatible one to help rectify the issue.
