Thanks for following along with the thread and sharing your concerns, @bbmhayes.

It looks like your attachment didn't post. Would you mind sharing that again so I can see exactly what's happening? 

In the meantime, I recommend following the guided steps my colleague shared above. Using an incognito/private browser will let us know if you have any issues with the saved cache in the browser. Web browsers collect cache to save time when loading repetitive data and images. Over time these files can become outdated and corrupted, causing issues like invoices not being sent. 

I'll be sure to keep an eye out for your reply. Please let me know if there is anything else I can assist you with. Chat with you soon!
