Hi @Rutian . You can't view if an invoice has been viewed in the Invoices app, but you can view this on the online platform. To do so, just hover over the invoice in your Invoices page.
Be aware, as opening the email and opening the actual invoice in the email are different functions, we're only able to show you if the invoice itself has been opened. Often a customer will open the email but not the invoice, in which case the status will still show as never viewed.
Noice. I do wish the app had it, but since I use the site to do most of my billing, it's fine. I do like that the app pushes notifications of opens though. That's a helpful bit. Also like that you allow for wikiesque markdown - old school, yo.
