I have uninstalled and reinstalled QuickBooks on my phone but it still is saving expenses as zero value when I have entered values.

Thanks for letting us know about this behavior, hornerfarm.

I would recommend contacting our Support team. That way, they can gather more details to investigate this further. They have more tools on their end.

In the meantime, you can sign in to your QBO company using your computer or mobile browser.

I'm just right here if you have other questions in mind.
