Thanks for visiting the Community, @abouttoshine. Let's work on this together to identify if you're going through a browser-related issue so we can get this resolved right away.
To confirm, log in to Quickbooks using a private or incognito window by opening any regular browser, then follow these shortcut keys below:
- Chrome simply press Ctrl + Shift + N.
- Mozilla Firefox and Internet Explorer, press Ctrl + Shift + P.
- Safari, press Command + Shift + N. Make sure you're using the latest version.
If you're able to run the mileage report successfully, that means that your default browser holds too much cache and temporary internet files that causing QuickBooks to behave unexpectedly. To fix this, go back to the regular browser and follow the steps to clear your browsing data.
If it's still an issue, try using another supported, up-to-date browser.
Let me know if there's anything else that you need help with. We're always delighted to provide our utmost assistance.
