My QB app is not syncing with my desktop version. Customers are missing invoices and estimates, can anyone help please?

Hello and welcome to the Community, Cmae

We're aware of an earlier issue with missing data on the app (including invoices and customers). To fix, please delete the app and install the latest version available in your mobile app store. 

If you continue to experience any issue, please get back in touch below with the operating system that you're using (iOS or Android). 

Thanks for reaching Intuit support. I'm just a post away if you have further questions or require additional assistance.
