iPhone app says This transaction contains details that need to be edited on the web

Thanks, it's all OK on the web, but I'm trying to find out WHY my last set of invoices will not show up on the app.

I hear you on this. Reaching out to our support team is the best way to get to the bottom of this issue. In the meantime, feel free to ask other questions, I'm here to help. 

I've figured it out. If I set "Online Payments" to "off" when making an invoice, the invoice shows up as normal. However, if it's left on and I can accept QBO Payments, the invoice has details that need to be viewed in a browser.

How strange that QB's own product causes this issue.
