Quickbooks Self Employed is not letting me add mileage... I add a trip, and its details, click save and it just disappears...

Hello there, aj5string.

We have an ongoing investigation about unable to create trips when using the QBSE mobile app. This is already investigated by our engineers and working for a fix. Temporarily, you can use a mobile browser (Desktop mode) or a computer browser.

If you're already using a browser to access QBSE, I'd recommend contacting our Customer Care Team. They can pull up your account and review the details. You can reach them through this link: Contact QuickBooks Self-Employed Support.

We appreciate your patience as we work on this.
