Why is mileage different between 2 points depending on whether you use the website or the iPad App? Even when using the iPad App the distance varies

Thanks for reaching out, aviation-edgingt. 

Let's get this sorted out so the Mileage feature is back on track. 

I recommend first checking that the device's operating system is up to date. This can help ensure that the auto-mileage tracking feature is properly working.

I'd also like to share a resource that can help you get familiar with the Mileage Tracking feature in QuickBooks Online. Our Community guides explain how to find and use each of the app's features. 

These article about mileage tracking would be a great one to start with:

• Automatically track mileage in QuickBooks Online
• Fix mileage tracking issues in the QuickBooks Online mobile app

Please let me know how things go on your end. I'll be here to lend a hand. Have a great day! 

It's not the auto-mileage tracking feature, it's when you manually add a trip. You type in the start address and the End Address, it the auto calculates the distance. However when I use it through the website QB Online the journey is a constant distance however when you add it manually in the iPad App then the distance is lower than the Website calculation. Yes, I am using the exact same addresses and on the iPad the distance between them can vary. 
Yes, my iPad OS is up to date.

Surely that wrong? Only just found out, but as result I have paid the incorrect amount as expenses. Possibly costing me a lot of money.

Hello, aviation-edgingt. 

To isolate the issue, I'd like to make sure this isn't a problem with the browser. I recommend clearing the cache, since it can sometimes become full of older data, potentially causing viewing errors in QuickBooks Online. Clearing the cache will allow you to work with a clean slate and resolve errors like this. This article will walk you through the steps depending on which browser you're using: Clear cache and cookies to fix issues when using QuickBooks Online. 

If the same problem occurs, try using a different browser. This can be an issue with the browser that you use and QuickBooks.      

If the same things happen, I suggest contact our QuickBooks Support, so they can investigate this.  

Please refer to this article to mobile app not tracking trips properly: Fix mileage tracking issues in the QuickBooks Online mobile app. 

Let me know how it goes by leaving a reply below. I'm here to help you further with tracking mileage in QuickBooks Online. Take care!

Using the website on 2 different computers 3 different browsers and they all calculate the distance the same 47.17mi however for a while I was entering the trips manually into the iPad App and that is where the problem is the App not the website. Using my SatNav and Google Maps 47.17mi is correct.

I do not use the tracking feature in the app because I'm a pilot, it seems to think when I'm flying it should track the mileage. It's manually entering them that is the problem, the app seems to vary the distance for no good reason

Hello aviation, Thanks for that. Could you provide a screenshot of an example in the app, so we can do some testing as to where this is coming from in the manual calculation of the mileage distance? 

Thanks for the screenshots, can we ask if you delete the trip and then enter it manually again does it still have the incorrect miles?
