I’m having a problem when adding amounts, it only allows me to add quantities of 0.99 or less, is it something I’m doing or is it the app?

That's a good question, charm1996.

Let's find out if this behavior only happens on the app or when you're using a browser as well.

Please sign in to QuickBooks using a mobile browser or your computer's browser, and try creating transactions to see if you can enter rates more than 0.99. If the same thing happens, please contact our QuickBooks Online Support, so they can investigate this behavior.

If this only happens on the app, please clear the app's cache, or re-install it.

Let me know how the steps work for you. I'm just around to continue to help.

On my laptop there’s no issue but on my phone, as you can see on the video attached, it still doesn’t work even after reinstalling the app. I tried contacting customer support but it tells me it’s unavailable.
