Hello, Neil. This can sometimes happen when cached data in the app becomes outdated or cluttered, which can interrupt the connection between your mobile device and the QuickBooks servers. To resolve this, please try refreshing the app data based on your device type.
For Android:
Navigate to Menu > More Options > Settings > Refresh Data, then select YES to confirm.
For iPhone:
Go to your device Settings > General > iPhone Storage > find the QuickBooks Online app > select Offload App. This clears outdated data while keeping your documents and files safe.
If these steps do not resolve the issue, I recommend contacting our QBO Live Support team. They have the tools necessary to look further into the underlying cause of the issue.
In the meantime, you can open QuickBooks in a supported web browser and attach photos and documents to your invoices there. This will help you stay on track and prevent any further delays.
Should you have any other concerns, feel free to reply to this thread.
