When adding an expenses from the transactions list on my mobile. It won’t show any expense category only asset and liability. It did before but not now.

Hi -rstokes-co-uk, thanks for dropping by on the QuickBooks Community

Please try deleting the app and then install the latest version available in your app store to troubleshoot. 

If you're still unable to select an expense category following this, please get back in touch below with the mobile version you're using (iOS or Android).
